Ohio CDL Permit Test - Tank

All drivers must be trained in the security risks of hazardous materials transportation. This training must include how to recognize and respond to possible security threats. Hazardous materials employees must be trained and tested at least once every three years.

When inspecting any kind of tank, it is most important to check the tank for leaks. It is illegal to transport any gas or liquid in a leaking tank.

In low temperatures, bridges usually freeze before other road surfaces. When driving in cold weather, especially when weather conditions have been wet, use special caution on bridges and overpasses.

Combination vehicles require more space on the road than other vehicles. When entering or crossing traffic while driving a combination vehicle, it is especially important that there is a large enonugh gap in traffic to safely do so.

Placards must be placed on the front, the rear, and both sides of a vehicle carrying hazardous cargo. They must be readable from any direction.

As the temperature begins to rise and ice on the road begins to melt, the road surface will often become even more slippery. Water from the slight melting will sit on top of the ice, decreasing the available traction even more. Always decrease your speed and drive with caution when traveling on slippery surfaces.

An empty combination vehicle will come to a complete stop more slowly than a fully-loaded vehicle. With less weight in a trailer, the stiff suspension springs and strong brakes will have lower traction than they would if the vehicle carried more weight.
