Texas CDL Permit Test - Special Requirements

If you are operating a large vehicle, be especially cautious when passing a motorcycle or bicycle. Since they are much lighter than other vehicles, they're more prone to be negatively affected by the wind created by large vehicles.

Generally, school buses carrying passengers should stop before passing over railroad grade crossings. The driver should ensure there are no trains coming from either direction before continuing. However, if an officer directs the driver to continue over the tracks without stopping, the driver should follow the officer's direction.

On trucks, truck tractors, semitrailers, pole trailers, and buses that are at least 80 inches in width, reflectors should be placed between 24 and 60 inches from the ground. Be sure to know the reflector requirements for your specific vehicle.

If lighted lamps are not required to be used during an emergency stop, they should be replaced by two red flags. If a semitrailer must be parked on the shoulder of a two-way roadway and flags are being used in the place of lighted lamps, the flags should be placed 100 feet in front of and behind the vehicle.

When driving a commercial motor vehicle down a hill, you should control the speed by switching into a low gear and supplementing with engine braking. It would be unlawful to coast the vehicle down the grade.

If a driver needs to haul a load that is heavier, longer, wider, or higher than is legally permitted, the driver must first obtain a special permit. If the load is seen as being easy to dismantle, the permit will not be granted.

If it is necessary to park in a driveway, you should enter the driveway by backing into the space. This way, when leaving the driveway, you can pull forward and clearly see where you are going.
