1. School buses:

In general, school buses manufactured after 1998 or 1999 must be equipped with an Anti-Lock Braking System (ABS). Many older buses are equipped with ABS as well.

2. If a driver needs to exit a school bus to ensure all waiting students have boarded, the driver should:

While students are boarding a school bus, if the driver cannot account for a student outside, they should secure the bus, take the key with them, and check around and underneath the bus for the missing student.

3. If your bus has a manual transmission, what should you never do when crossing railroad tracks?

Do not shift gears while crossing railroad tracks. Your vehicle could stall and get stuck in the crossing.

4. During a basic vehicle control skills test, a look is when:

A driver uses a look when they open their door, leave their seated position, and walk to the back of the vehicle to check its position. During the straight line backing exercise, a driver may not exceed one look. During any other exercise, a driver may not exceed two looks.

5. If a tornado is approaching and there is no nearby shelter, where should students go?

If students are evacuated due to a school bus being in the direct path of a sighted tornado, the driver should lead them to shelter in a nearby building. If no such shelter is available, the driver should escort them to a nearby ditch or culvert. They should avoid areas that may be subject to flash flooding and should be far enough away from the bus that it would not fall on them if it tipped over.

6. Loading and unloading a bus:

More students are killed each year during loading or unloading of school buses than while riding on school buses. Therefore, it is critical that school bus drivers follow appropriate safety procedures during loading and unloading.

7. When completing a driver's side parallel parking maneuver, you should:

You may be asked to complete a parallel parking maneuver into a parking space that is to the left of your vehicle. You should drive past the parking space before backing into it while bringing the rear of your vehicle as close to the rear of the space as possible. Your vehicle should be completely within the boundaries of the space.
