To avoid a loss of control, you should accelerate slowly when driving in poor-traction conditions, such as rain or snow.

When driving a bus, you should be mindful of the size of the gap that your vehicle will need to merge into traffic after making a stop. Wait for a gap of the necessary size to open in passing traffic before re-entering the main road.

For safe operation, a commercial motor vehicle needs a tread depth of 4/32 of an inch in every major groove on the front tires, and a tread depth of 2/32 of an inch on other tires.

At bus stops, drivers should warn passengers about potential hazards. This may include warning them to watch their step when exiting the bus by way of lowered stairways.

When backing, you should pull forward to reposition your vehicle whenever needed. Drift should be corrected immediately by turning the steering wheel in the direction of the drift.

A vehicle will be slowed down by gravity on any uphill grade. You may need to switch to a lower gear to climb a steep grade.

Bridges tend to freeze before other parts of the road surface. You should be especially careful on bridges when temperatures are near the freezing point.
