When should you leave your parking brakes on?

1. Always, regardless of the situation

2. Never, it's unsafe

3. If parking on a 2 way road with a limit exceeding 30mph

4. Only if parking on a hill

The correct answer is: If parking on a 2 way road with a limit exceeding 30mph

Leaving your parking brakes on is not always necessary, as it may be unsafe or unnecessary in certain situations. It is important to turn off your parking brakes if they are not needed to avoid damage to your vehicle and wastage of fuel. Option A is incorrect because leaving your parking brakes on at all times can lead to unnecessary wear and tear on your brakes and decrease fuel efficiency. Option B is incorrect because there are situations, such as parking on a steep hill, where it is necessary to engage the parking brake for safety reasons. Option D is also incorrect as parking brakes are not only needed for parking on a hill, but also in situations where there is a risk of the vehicle rolling or moving, such as on a 2 way road with a speed limit over 30mph. Option C is the correct answer as it provides a specific scenario where using parking brakes is necessary.
