45 . Why are roads especially slippery right after it begins to rain?
Tires are not usually designed to drive in rain.
In rainy weather, roads are often at their most slippery when the rain first begins to fall. Fresh rainwater mixes with oil and grease on the road to form a slick film. As the rain continues, this mixture will eventually wash away.
46 . To confirm that a trailer has ABS, you can:
Remove a tire and look for the ABS sensor on the axle.
If you are unsure if a trailer is equipped with an Anti-Lock Braking System (ABS), look under the vehicle for the electronic control unit and wheel speed sensor wires coming from the back of the brakes.
