Why should a front passenger keep their feet off the dashboard?

552. Why should a front passenger keep their feet off the dashboard?

It can prevent the passenger airbag from deploying.
✓ It can greatly increase the risk of injury if the airbag deploys.
It can interfere with the rear-view mirror.

A front airbag deploys very quickly and with considerable force. If a passenger has their feet or legs on the dashboard, airbag deployment can force their legs backwards and greatly increase the risk of serious injury. Passengers should sit normally with their feet in the footwell and wear their seat belts correctly. The driver should make sure everyone is seated and restrained safely before setting off.

How should you normally brake on a motorcycle?

597. How should you normally brake on a motorcycle?

Use only the front brake.
Use only the rear brake.
✓ Use both brakes smoothly and progressively.
Apply both brakes as suddenly as possible.

How can higher speed affect fuel or energy consumption?

599. How can higher speed affect fuel or energy consumption?

✓ It can increase consumption because air resistance rises.
It always reduces consumption.
It has no effect once the vehicle is moving.
It reduces aerodynamic resistance.

As speed increases, aerodynamic resistance generally rises, so the vehicle needs more energy to maintain that speed. Driving smoothly at an appropriate speed can therefore reduce fuel or energy consumption.
