Problems to check for when inspecting tires include: air pressure that is too low or too high; using radial and bias-ply tires together; tread depth of less than 4/32 of an inch in major grooves on front tires; and tread depth of less than 2/32 of an inch on all other tires.
Employees who work with hazardous materials must be trained and tested at least once every three years.

Factors that can affect stopping distance include your vehicle's speed, its weight, and how slippery the road surface is.
The shipper of hazardous materials is responsible for packaging, marking, and labeling the materials. They must supply any necessary placards.
