the tracks are not clear.
there is oncoming traffic.
there is no oncoming traffic.
5. What is an important thing to remember about emergency braking?

usually have a person directing traffic.
should never be crossed using a CMV.
have at least one traffic control device.

Perception distance, reaction distance and braking distance
Braking distance + stopping distance
Reaction distance + viewing distance + braking distance

check that the lightest parts of the cargo are under the heaviest parts.
check that you do not exceed gross weight and axle weight limits.
check that the content matches the description on the shipping paper.
make sure the cargo is piled up high.

The minimum tread depth may vary.
Air pressure increases with temperature.
Hydroplaning is more likely if tire pressure is low.
All of the above.

slow down to the posted speed limit for the off ramp.
get on the curved part of the off ramp, then brake and turn at the same time.
