Use only your low beam headlights.
If the interior of your cab is too bright when you are driving at night, you may have difficulty seeing things outside. Keep the interior light off and adjust your instrument lights to the lowest possible level that still allows you to easily read the gauges.
39 . A commercial motor vehicle should:
Always be equipped with at least one fire extinguisher.
Vehicles must be equipped with the appropriate emergency equipment. When inspecting a CMV, you should check for at least one fire extinguisher; spare electrical fuses, unless the vehicle is equipped with circuit breakers; and the appropriate warning devices to be used when the vehicle is parked.
40 . Which of the following is not a good way to reduce crashes when turning right?
Allow open space on your right side.
When making a right turn, avoid turning too wide to the left. If you must swing into another lane to complete the turn, you should keep the rear of your vehicle close to the curb. Leaving space to the right of your vehicle while turning right may indicate to other drivers that you are turning left, so they may attempt to pass you on your right.

Drive on the shoulder.
If you see, hear, smell, or feel anything that could indicate trouble while you are driving, you should stop and inspect the source of the unusual occurrence.
