1. When stopping a manual transmission vehicle, you should:

Explanation
When stopping, apply gradual pressure to the brake pedal and stop smoothly. If stopping a manual transmission vehicle, push the clutch in when the engine is close to idle.

2. Before entering a curve, you should:

Explanation
Always downshift before entering a curve. Decreasing your speed before entering the curve will allow you to maintain better control over the vehicle throughout the curve.

3. Having ABS on only one axle:

Explanation
If you have an Anti-Lock Braking System (ABS) equipped on only the tractor, only the trailer, or only one axle, you will still have more control over the vehicle when braking than you would without ABS. You should brake normally.

4. If a traffic light has been green for a long time:

Explanation
If you are approaching a traffic light that has been green for a long time, there is a good chance that it will turn yellow before you reach it. Start slowing down and be ready to stop.

5. When a combination vehicle goes around a corner:

Explanation
When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called off-tracking. This effect is especially pronounced on vehicles with trailers.

6. When starting a vehicle, warning lights and buzzers:

Explanation
After starting a vehicle's engine, the warning lights and buzzers should turn on, then quickly turn off.

7. You should check and adjust your mirrors:

Explanation
Be sure to check your mirrors before beginning a drive. Your posture may change day to day and your mirrors may need to be adjusted.
