Not use the brakes.
When backing a straight truck, you would turn the wheel in the direction you want to go.

Once your trailer starts to turn, you should turn the steering wheel the other way to follow the trailer.

47 . In an emergency, if you must leave the roadway to drive on the shoulder, you should:
Stay on the shoulder until the next exit.
If a hazard requires you to drive onto the shoulder of a road, you should try to keep one set of wheels on the pavement to maintain better control of your vehicle. If possible, stay on the shoulder until your vehicle has come to a complete stop, then pull back onto the road when it is safe to do so.
48 . To correct a drive-wheel braking skid, a driver should do all of the following, except:
Accelerate.
To correct a drive-wheel braking skid, you should first remove your foot from the brake pedal to allow the locked wheels to begin rolling again. Quickly steer in the direction you want to go, then countersteer to prevent your vehicle from skidding in the opposite direction.
49 . If you are turning left where there are two available turning lanes:
You should use both lanes.
If making a left turn where there is more than one available turn lane, you should always choose to take the rightmost lane. Large vehicles often have to swing right to make left turns, so it is safer for you to have other left-turning traffic to your left. This will allow you to have the best possible view of other turning vehicles and will lower the risk of your vehicle colliding with them.
50 . If you are experiencing an engine fire, you should:
Turn on the heater.
In the event of an engine fire, you should turn off the engine as soon as possible. Do not open the hood unless absolutely necessary. Using a fire extinguisher, shoot foam through the louvers or radiator, or from the vehicle’s underside. If you are unsure of how to treat a fire, wait for firefighters to arrive.
