How safely you can drive starts with the vehicle. It's your duty to make sure the car you drive is safe: a car in bad shape can break down, cause a crash, or fail you in an emergency. A few simple checks prevent most trouble.

Equipment to check: lights, brakes, wipers, horn, mirrors, safety belts and glass

Have a mechanic check your brakes if:

  • They don't seem to be working properly
  • They make a lot of noise or give off an unusual odor
  • The brake pedal goes to the floor
  • The vehicle pulls to one side when you brake
Handbook p. 13 ↗

Know the rule

Check turn signals, brake lights, taillights and headlights from outside the vehicle. An out-of-line headlight can blind other drivers; if you have trouble seeing at night or others often flash their lights at you, have the headlights checked.

Handbook p. 13 ↗

Know the rule

Clear snow, ice and frost from all windows before driving. Replace wiper blades that don't clear water well, keep the washer bottle full, clean the inside of the glass, and replace a damaged windshield.

Handbook p. 13 ↗

Know the rule

Worn or bald tires increase stopping distance, make turning harder on wet roads, increase hydroplaning, and raise the chance of a flat. Unbalanced tires and low pressure cause faster wear, lower fuel economy, and make steering and stopping harder.

Handbook p. 13 ↗

Know the rule

Find the recommended tire pressure (psi) in the owner's manual or on the driver's side door jamb, and check it with a tire pressure gauge. Check tires for wear and damage once every month or before a long trip.

The penny test for tread wear:

  • Hold the penny with Lincoln's body between your thumb and forefinger
  • Put Lincoln's head into a groove where the tread looks lowest
  • If any part of Lincoln's head is covered by tread, you have a safe amount of tread

Time to fix the problem and get rechecked if your vehicle fails an emissions inspection

Handbook p. 13 ↗

Know the rule

If the vehicle bounces a lot after a bump or stop, or is hard to control, you may need new shocks or other suspension parts.

Handbook p. 14 ↗

Know the rule

Exhaust leaks can kill people inside a vehicle in a very short time. Never run the motor in a closed garage, and open a window if you sit in a running vehicle for a long time. Many leaks can't be heard, so have the exhaust checked periodically.

Handbook p. 14 ↗

Inside the vehicle:

  • Steering hard to turn, or not turning when the wheel first turns? Have it checked
  • Use the horn only as a warning to others
  • Fasten your belt; make sure all passengers use belts or child restraints
  • Adjust seat and mirrors before driving; set side mirrors so you just see your car's side when leaning forward
  • Secure loose objects; nothing on the floor that could roll under the brake pedal
  • After-market changes such as tinted windows and lighting may violate legal standards
Handbook p. 14 ↗

Know the rule

Burning fuel releases carbon dioxide (CO2), which the EPA says contributes to climate change. Buy smart (research emissions and fuel economy) and drive smart to improve fuel efficiency.

Handbook p. 14 ↗

Put it into practice

When you press the brake, your car drifts to the right and the pedal feels soft. That signals a problem in the braking system — have a mechanic check it before driving further.

Check your understanding

Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.

A driver's vehicle pulls to one side when the brake is applied. What does this suggest?
  1. Worn suspension shocks
  2. An exhaust system leak
  3. Normal tire wear that can be ignored
  4. A braking problem needing service

Answer: A braking problem needing service

If the vehicle pulls to one side when braking, this indicates a braking system problem that should be serviced.

Handbook p. 13 ↗
According to the manual's 'penny test,' what does it mean if any part of Lincoln's head is covered by tire tread?
  1. Your tires need immediate replacement
  2. Your tires are overinflated
  3. Your tires are illegal to drive on
  4. You have a safe amount of tread

Answer: You have a safe amount of tread

If any part of Lincoln's head is covered by the tread, you're driving with a safe amount of tread.

Handbook p. 13 ↗
Worn or bald tires primarily increase which two things?
  1. Fuel economy and top speed
  2. Stopping distance and difficulty turning on wet roads
  3. Engine power and acceleration
  4. Tire pressure and ride comfort

Answer: Stopping distance and difficulty turning on wet roads

Worn or bald tires can increase your stopping distance and make turning more difficult when the road is wet.

Handbook p. 13 ↗
If your vehicle fails an emissions inspection, how many days do you have to fix the problem and get it rechecked?
  1. 30 days
  2. 10 days
  3. 60 days
  4. 90 days

Answer: 60 days

If the vehicle fails, you are given 60 days to fix the problem and have the emissions rechecked.

Handbook p. 13 ↗
What should you do if your vehicle's brake pedal goes to the floor?
  1. Pump the brakes and keep driving
  2. Have a mechanic check the brakes
  3. Add brake fluid yourself and keep driving
  4. Rely on the parking brake until it improves

Answer: Have a mechanic check the brakes

If the brake pedal goes to the floor, makes noise, or emits an odor, have a mechanic check the brakes.

Handbook p. 13 ↗
After-market changes to a vehicle, such as tinted windows, may violate legal standards.
  1. True
  2. False

Answer: True

Aftermarket changes to equipment such as tinted windows and lighting may violate legal standards.
