4 Steps to Protect Children

Securing our Most Precious Cargo
Motor vehicle crashes are the leading cause of death among children ages 2 to 14, due in large part to the nonuse or improper use of child seats and seat belts. Working with parents and our partners our goal is to ensure every child is properly secured and safe every trip, every time.


Parents - Not Sure Which Car Seat to Use?
Are you looking for a new car seat for your infant, toddler or 4-8 year old child but overwhelmed by the choices and worried about how to properly install your car seat? Our 4 Steps for Kids campaign will help you properly choose and install the correct car seat for your child. Simply click on the link below that best matches your child.

REAR-FACING SEATS

Infants - from birth to at least 1 year old
For the best possible protection keep babies in the back seat, in rear-facing child safety seats, as long as possible up to the height or weight limit of the particular seat. At a minimum, keep babies rear-facing until a minimum of age 1 and at least 20 pounds.

FORWARD-FACING TODDLER SEATS

Toddlers - Age 1 & 20 lbs to Age 4 & 40 lbs
When children outgrow their rear-facing seats (at a minimum age 1 and at least 20 pounds) they should ride in a forward-facing toddler seat, in the back seat, until they reach the upper weight or height limit of the particular seat (usually around age 4 and 40 pounds).

BOOSTER SEATS

Children - from about age 4 to at least age 8
Once children outgrow their forward-facing seat (usually around age 4 and 40 pounds), they should ride in booster seats, in the back seat, until the vehicle seat belts fit properly. Seat belts fit properly when the lap belt lays across the upper thighs and the shoulder belt fits across the chest (usually at age 8 or when they are 4'9” tall).

SAFETY BELTSTweens - age 8 and older
When children outgrow their booster seats, (usually at age 8 or when they are 4'9” tall) they can use the adult seat belt in the back seat, if it fits properly (lap belt lays across the upper thighs and the shoulder belt across the chest).

The Crash Tests and Dummies

Road traffic accidents takes lives of more than one million people a year, injuring another thirty-eight million (5 million of them seriously). The death rate of the world's roadways makes driving the number one cause of injury and death for young people ages 15 to 44 years.
How safe is that a used or a new automobile you are thinking of purchasing? With the inventions of the airbags and crash testing, the numbers of citizens injured and killed by vehicles has decreased in many nations.
A crash test is a form of destructive testing usually performed in order to ensure safe design standards in Crash worthiness and crash compatibility for automobiles or related components.
The Crash tests are done under very careful safety and scientific standards. Every crash test is very costly so the maximum amount of data must be got from each and every test. Typically, this requires the usage of high-speed data-acquisition, at least one accelerometer and crash test dummies.
Two types of crash tests are been performed on each automobile – one is an offset frontal test and the other is side impact test. These tests suggest two of the most common crashes that occur on our roads.
Dummies are used to calculate the level of injury that would affect the front seat occupants wearing the safety belts in these crashes.
The crash-rating dummy represents an average-sized adult is been placed in the driver seat and rear passenger seats and secured with the vehicle's seat belts.
The mandatory standard for crash tests is to:
  • Reduce the level of risk to drivers, passengers and public by preventing supply of dummies that do not meet key safety requirements.
  • Reduce the incidence of serious injury associated with poor quality products.
  • Give consumers confidence that dummies available in the market have
  • a reasonable level of safety.
  • Provide a framework for industry to determine appropriate levels of safety for dummies.

Choose a Qualified Dealer to Modify Your Vehicle

Even a half inch change in the lowering of a van floor can affect a driver's ability to use equipment or to have an unobstructed view of the road; so, take time to find a qualified dealer to modify your vehicle. Begin with a phone inquiry to find out about credentials, experience, and references. Ask questions about how they operate. Do they work with evaluators? Will they look at your vehicle before you purchase it? Do they require a prescription from a physician or other driver evaluation specialist? How long will it take before they can start work on your vehicle? Do they provide training on how to use the adaptive equipment? If you are satisfied with the answers you receive, check references; then arrange to visit the dealer's facility. Additional information to consider is listed below.

Are they members of the National Mobility Equipment Dealers Association (NMEDA) or another organization that has vehicle conversion standards?
  • What type of training has the staff received?
  • What type of warranty do they provide on their work?
  • Do they provide ongoing service and maintenance?
  • Do they stock replacement parts?
Once you are comfortable with the dealer's qualifications, you will want to ask specific questions, such as:
  • How much will the modification cost?
  • Will they accept third party payment?
  • How long will it take to modify the vehicle?
  • Can the equipment be transferred to a new vehicle in the future?
  • Will they need to modify existing safety features to install the adaptive equipment?
While your vehicle is being modified, you will, most likely, need to be available for fittings. This avoids additional waiting time for adjustments once the equipment is fully installed. Without proper fittings you may have problems with the safe operation of the vehicle and have to go back for adjustments.

Tire Maintenance

There is a close working relationship between your tires and other mechanical systems in your vehicle, such as the wheels, brakes, shock absorbers, steering and suspension systems. To ensure you have a safe, comfortable ride and good tire mileage, click on the areas of interest below.

Tire Size
To maintain tire safety, purchase new tires that are the same size as the vehicle's original tires or another size recommended by the manufacturer. Look at the tire information placard, the owner's manual, or the sidewall of the tire you are replacing to find this information. If you have any doubt about the correct size to choose, consult with the tire dealer.

Tire Tread
The tire tread provides the gripping action and traction that prevent your vehicle from slipping or sliding, especially when the road is wet or icy. In general, tires are not safe and should be replaced when the tread is worn down to 1/16 of an inch. Tires have built-in treadwear indicators that let you know when it is time to replace your tires. These indicators are raised sections spaced intermittently in the bottom of the tread grooves. When they appear "even" with the outside of the tread, it is time to replace your tires.

Another method for checking tread depth is to place a penny in the tread with Lincoln's head upside down and facing you. If you can see the top of Lincoln's head, you are ready for new tires. The tread on this tire covers the top of Lincoln's head, so it's not yet ready for replacement.


Balance & Alignment
To avoid vibration or shaking of the vehicle when a tire rotates, the tire must be properly balanced. This balance is achieved by positioning weights on the wheel to counterbalance heavy spots on the wheel-and-tire assembly.

A wheel alignment adjusts the angles of the wheels so that they are positioned correctly relative to the vehicle's frame. This adjustment maximizes the life of your tires and prevents your car from veering to the right or left when driving on a straight, level road.

These adjustments require special equipment and should be performed by a qualified technician.

Rotation
Rotating tires from front to back and from side to side can reduce irregular wear (for vehicles that have tires that are all the same size). Look in your owner's manual for information on how frequently the tires on your vehicle should be rotated and the best pattern for rotation.

Repair
A plug by itself is not an acceptable repair.

The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire that surrounds the puncture hole. The repair material used - for example, a “combination patch and plug” repair - must seal the inner liner and fill the injury to be considered a permanent repair.

Punctures through the tread can be repaired if they are not too large, but punctures to the sidewall should not be repaired.

Tires must be removed from the rim to be properly inspected before being plugged and patched.

Driving More Efficiently

Drive Sensibly
Aggressive driving (speeding, rapid acceleration and braking) wastes gas. It can lower your gas mileage by 33 percent at highway speeds and by 5 percent around town. Sensible driving is also safer for you and others, so you may save more than gas money.
Fuel Economy Benefit : 5-33%
Equivalent Gasoline Savings : $0.08-$0.55/gallon

Observe the Speed Limit
While each vehicle reaches its optimal fuel economy at a different speed (or range of speeds), gas mileage usually decreases rapidly at speeds above 60 mph.
You can assume that each 5 mph you drive over 60 mph is like paying an additional $0.24 per gallon for gas. Observing the speed limit is also safer.
Fuel Economy Benefit : 7-23%
Equivalent Gasoline Savings : $0.12-$0.38/gallon


Remove Excess Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.
Fuel Economy Benefit : 1-2%/100 lbs
Equivalent Gasoline Savings: $0.02-$0.03/gallon

Avoid Excessive Idling
Idling gets 0 miles per gallon. Cars with larger engines typically waste more gas at idle than do cars with smaller engines.

Use Cruise Control
Using cruise control on the highway helps you maintain a constant speed and, in most cases, will save gas.

Use Overdrive Gears
When you use overdrive gearing, your car's engine speed goes down. This saves gas and reduces engine wear.

what are HEVs?

Hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools, also known as HEVs or hybrids. Present-day hybrids are equipped with ICEs and electric motors. A hybrid's ICE engine, as in any ICE-powered car, produces power through continuous, controlled explosions that push down pistons connected to a rotating crankshaft. That rotating force (torque) is ultimately transmitted to the vehicle's wheels.

A hybrid's electric motor is energized by a battery, which produces power through a chemical reaction. The battery is continuously recharged by a generator that—like the alternator of a conventional car—is driven by the ICE.

Hybrids can have a parallel design, a series design, or a combination of both:

  • In a parallel design, the energy conversion unit and electric propulsion system are connected directly to the vehicle's wheels. The primary engine is used for highway driving; the electric motor provides added power during hill climbs, acceleration, and other periods of high demand.
  • In a series design, the primary engine is connected to a generator that produces electricity. The electricity charges the batteries, which drive an electric motor that powers the wheels. HEVs can also be built to use the series configuration at low speeds and the parallel configuration for highway driving and acceleration.
Some of the advanced technologies typically used by hybrids include

  • Regenerative BrakingThe electric motor applies resistance to the drivetrain causing the wheels to slow down. In return, the energy from the wheels turns the motor, which functions as a generator, converting energy normally wasted during coasting and braking into electricity, which is stored in a battery until needed by the electric motor.
  • Electric Motor Drive/Assist
    The electric motor provides additional power to assist the engine in accelerating, passing, or hill climbing. This allows a smaller, more efficient engine to be used. In some vehicles, the motor alone provides power for low-speed driving conditions where internal combustion engines are least efficient.
  • Automatic Start/Shutoff
    Automatically shuts off the engine when the vehicle comes to a stop and restarts it when the accelerator is pressed. This prevents wasted energy from idling.
