8 . Parts of an exhaust system should be:
Cracked.
When inspecting an exhaust system, you should verify that parts of the system are not loose, broken, or missing. The system's parts must be properly mounted and should not be rubbing against moving parts of the vehicle.
9 . Why are roads particularly slippery right after it begins to rain?
Some tires are not designed for rain.
Roads are often at their most slippery when rain is just beginning to fall. This is because water mixes with oil and grease on the road to create a slick surface. As rain continues, the oil and grease will wash away.
10 . What can happen if the air pressure gets too low in an air brake system?
The brakes will be very sensitive.
Pressing and releasing the brake pedal unnecessarily can let air out faster than the compressor can replace it, reducing the available air pressure. If the air pressure in an air brake system gets too low, the brakes will no longer work.
11 . If you don't know if there is enough space for your vehicle to pass under a bridge, you should:
Drive on the shoulder.
If you can't tell if your vehicle will have room to fit under a bridge or other overhead object, you should slow down and find an alternate route, if possible.

105,500 pounds
On state highways in North Dakota, the gross weight of a vehicle is limited to a maximum of 105,500 pounds, unless a lower limit is posted.

Easy to slide off.
When inspecting your vehicle's engine, check the belts for tightness and excessive wear. The amount of "give" that is safe for each belt in a given engine will vary, so learn what is appropriate for your vehicle.

53 feet
