Dense liquids require less outage than lighter ones

You must always fill dense liquids to the top

The tank may reach legal weight limits before it is full

3 / 10

You are driving a baffled tank vehicle and make a sudden stop. What effect do the baffles have on the liquid’s movement?

They prevent all liquid movement

They increase the risk of rollover

They reduce forward and backward surge

They eliminate side-to-side surge

4 / 10

You are driving a tank vehicle with a partially full load and approach a stop sign on an icy road. What could happen if you brake suddenly?

The tank will automatically stabilize itself

The liquid will freeze and prevent movement

The brakes will stop the vehicle instantly

Load the tank only at night

Fill the tank to the top to minimize surge

Leave enough outage to allow for expansion

Add extra liquid to compensate for expansion

10 / 10
