3. A convex mirror is sometimes called a ____ mirror.

Bug-eye

Square

Helper

Large vehicles often have curved, convex mirrors, sometimes referred to as "fisheye," "spot," or "bug-eye" mirrors. These mirrors provide a wider view than flat mirrors. However, they also make objects seem smaller and farther away than they actually are.

4. If a vehicle is equipped with power steering, you should inspect:

Both of the above.

When inspecting a vehicle with power steering, check the hoses, pumps, and fluid level. In particular, you should look for leaks in the hoses.

When inspecting a vehicle, you should ensure that dual tires do not come into contact with each other or with other parts of the vehicle. Tire sizes should not be mismatched, and tires should not be cut or damaged in any way. Regrooved, recapped, or retreaded tires are not permitted to be used on the front wheels of a bus.

6. A highway curve should be taken:

At or slightly above the posted speed limit.

At the posted speed limit.

Well below the posted speed limit.

Due to a high center of gravity, tank vehicles are especially prone to tipping over in turns and curves. To counteract this, you should take curves and ramps at speeds that are well below the posted limits.

7. If other vehicles are having a difficult time getting around your truck on a road with two or more lanes, you should:

Speed up.

Drive on the shoulder.

Use the right lane.

You should stay in the right lane of a multilane road if your vehicle is being slowed down by a heavy load. Allow other vehicles to pass your truck using the left lane.
