A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.

You should slow down when driving a school bus in high winds. Keep a strong grip on the steering wheel and try to anticipate gusts.

A dual air brake system has two separate air brake systems that use a single set of brake controls. One system typically operates the regular brakes on the rear axle or axles. The other system operates the regular brakes on the front axle.

Railroad crossings that do not display any traffic control devices are known as passive crossings. The decision to proceed across tracks at a passive crossing is entirely up to the driver.

You should avoid refueling a bus while passengers are on board, unless it is absolutely unavoidable. You should never refuel a bus with passengers on board while inside an enclosed building.

Dry bulk tanks require special care when being driven because they have high centers of gravity. Drivers should also be careful because the materials being carried can easily shift in transit, causing a change in the vehicle's handling.

During the on-road driving test, if your route does not include a railroad crossing, the examiner may ask you to explain and demonstrate the necessary procedures at a simulated location.

Once students have boarded a school bus, the driver should wait to move the bus until all of the passengers are seated and looking forward.
