What should you do when parking next to the kerb while facing downhill?

Answer: A — Apply the handbrake

When parking next to the kerb while facing downhill, it is essential to apply the handbrake. This action helps secure the motorcycle in place, preventing it from rolling down the slope due to gravity. The handbrake provides stability and ensures that your motorcycle remains stationary while parked. Turning the wheels away from the kerb is a technique typically used when parking uphill, as it serves to prevent the vehicle from rolling into the road if it were to move. Leaving the engine running can be unsafe and is generally discouraged as it not only wastes fuel but can pose a risk of accidents or emissions issues. Parking with the door open is not a practical or safe practice while the motorcycle is stationary as it obstructs space and can be hazardous. Therefore, applying the handbrake is the best and safest practice when parking downhill.
