Bearing plates

Which of the following should you NOT do if you experience a tire failure? Brake hard and immediately. Be aware that a tire has failed. Hold the steering wheel firmly. Stay off the brake pedal.

Brake hard and immediately. Hard braking could cause your vehicle to go out of control, so brake gently only after the vehicle has slowed down and you have regained control.

During the vehicle inspection test, you must be able to do all of the following, except: Show where the power steering fluid dipstick is located. Check for adequate power steering fluid. Ensure that the power steering fluid level is above the full mark.

Ensure that the power steering fluid level is above the full mark. During the pre-trip vehicle inspection test, you will be asked to indicate where the power steering fluid dipstick or reservoir sight glass is located. You will need to show that the power steering fluid is within a safe operating range.

Every two hours or every 100 miles. Air pressure increases with temperature. When driving in very hot weather, inspect the tires every two hours or every 100 miles. Use a tire pressure gauge to get an accurate reading. However, even if the tires have become overinflated from the heat, do not let air out because the pressure will drop too low when the tires cool. If a tire is too hot to touch, remain stopped until it cools. Otherwise, it may blow out or catch fire.

Four times as much.. When you double your speed, your braking distance increases by roughly the square of the speed increase - to about four times as much as before. For example, increasing your speed from 15 to 30 mph will increase your stopping distance from 46 to 148 feet.

What should you do if you doubt you have safe space to pass under a low bridge? Increase the weight of your vehicle to clearing under the bridge. If no warnings are posted, assume there is enough clearance under the bridge and proceed slowly. Go slowly, and take another route if you are not sure you can make it.

Go slowly, and take another route if you are not sure you can make it.
