Should be expected to be on the roadway.

Is usually empty and harmless.

Could contain a heavy object that could damage vehicles.

Almost any foreign object on the road poses some potential danger. For example, even something as seemingly harmless as a cardboard box could contain a hard or heavy object that could damage your vehicle.

2 . Livestock:

Should never be carried on a trailer.

Should be placed in the front of a trailer.

Can create unstable driving conditions.

Because live animals can lean during curves, and otherwise move in transit, the weight distribution of a cargo of livestock is unstable. Driving with livestock requires special care.

3 . On any upgrade, gravity will:

Speed your vehicle up.

Slow your vehicle down.

Not impact your speed.

A vehicle will be slowed down by gravity on any uphill grade. You may need to switch to a lower gear to climb a steep grade.

By exercising.

At a fixed rate.

More quickly if the person stays awake.

The liver removes alcohol from the body at a fixed rate. Despite popular belief, tricks like drinking coffee or taking a cold shower will not speed up the process. The only way to become sober is to allow your body the time it needs to remove the alcohol from your system.

Continue to drive.

Pull over and figure out what's wrong.

Run the air conditioner.

If the coolant temperature gauge goes above the highest safe temperature, you should stop driving as soon as possible and try to figure out what is wrong. There could be an issue in your vehicle that could lead to engine failure and possibly a fire.

7 . If you see taillights ahead while you are driving in fog:

The lights may not indicate where the road is as the vehicle may have pulled off the roadway.

You can assume the vehicle ahead is on the road.

It may be an optical illusion.

When driving under foggy conditions, lights cannot be taken as a reliable indication of where the road is. The lights may be coming from a vehicle that has pulled off the road.
