1 . If using a helper while backing a vehicle, where should they stand?
Near the back of the truck
If you use a helper while backing your vehicle, they should stand near the back of the vehicle in a place where they are visible to you. Before backing, work out a set of hand signals that both you and your helper understand. Agree on a signal for "stop."
2 . Move over laws require:
All vehicles to move to the left lane if a flatbed trailer is in the right lane.
If an emergency vehicle with its lights on is stopped on the side of the road, move over laws require drivers to vacate the lane directly next to the vehicle, if possible. If a driver cannot move over safely, they must slow down and proceed with caution.
3 . Stopping distance can be affected by:
Traffic.
Stopping distance is affected by a vehicle's speed. The faster you are driving, the longer your stopping distance will become.
4 . When checking your tires, which of the following is not an issue to correct?
Tread depth of at least 4/32 of an inch on the front tires
Problems to check for when inspecting tires include: air pressure that is too low or too high; using radial and bias-ply tires together; tread depth of less than 4/32 of an inch in major grooves on front tires; and tread depth of less than 2/32 of an inch on all other tires.
5 . Roads are most slippery right after it begins to rain because:
Some tires are not designed for rain.
Roads are particularly slippery when it first begins to rain. The water mixes with oil drippings on the road that have not yet washed away, creating a slippery and dangerous mixture.
6 . If you are being tailgated, you should:
Allow the vehicle to pass.
If someone is tailgating you, it is a good idea to open up the space ahead of your vehicle to make it easier for the driver to pass you. Increasing your speed is not a good idea because the driver may continue to tailgate you at the higher speed, only increasing the danger.
7 . Rims with welding repairs:
Are acceptable in combination vehicles.
