2 . When approaching a vehicle for a pre-trip inspection, a driver should look under the vehicle:

When approaching your vehicle before an inspection, make note of its general condition and ensure that it is not damaged or leaning. Look under the vehicle for fresh leaks of oil, grease, or fuel. Check around the vehicle for hazards to movement, such as people, other vehicles, or low-hanging wires or tree limbs.

An Anti-Lock Braking System (ABS) helps prevent wheels from locking up during a hard application of brakes.

For your own safety, when placing reflective warning triangles, you should carry them between your body and the oncoming traffic.

Distractions while driving can be physical (such as reaching for an object), mental (such as making conversation with a passenger), or both (such as holding a phone to send texts).
