K53 vehicle controls explained
What the controls of your vehicle do and the correct order of operation.
Vehicle controls are the smallest section of the test, but they have their own pass mark, so you cannot skip them. These chapters cover what each control does, how to use them together and the steering and braking systems.
Vehicle controls and their functions
A vehicle control is a device the driver or rider uses to operate the vehicle, such as a steering wheel, brake or indicator switch. Instruments such as the speedometer display information; mirrors help you observe traffic. Learning their names and purposes is more useful than memorising numbers.
- Identify the pictured device by its job, then read the diagram label.
- Power control and braking are different functions; leave enough stopping space.
- The clutch disengages drive; the lever selects the gear.

Steering and braking systems
Steering changes the vehicle’s direction. Braking reduces its speed or secures it when stationary. These systems must operate safely and efficiently; excessive looseness, sticking, damage or ineffective brakes are not acceptable simply because a journey is short.
- Steering changes the vehicle’s direction.
- Do not begin the journey.
- Apply the full rule to the actual vehicle, road and conditions.
Rules in detail: Brakes, hooter and warning devices
What the rule says. You may not ride a motorcycle on a public road unless it has two independent braking systems. One must act on the front wheel and the other on the rear wheel or wheels. The brakes must be in good working order.
- Two independent brakes: one on the front wheel, one on the rear.
- Service, parking and emergency brakes, with the last two allowed to be one brake.
- Hoot only for safety; the hooter must be audible from 90 metres.

Practice questions on vehicle controls
1 What must be true of a vehicle’s steering system?
- It works only above 60 km/h
- It allows safe and efficient steering
- It may stick if the road is straight
Show the answer
Answer B: It allows safe and efficient steering
Steering must be in a condition that allows safe and efficient control. A motorcycle needs independent front and rear braking systems in working order. Light and heavy vehicles require working service, parking and emergency braking; the emergency and parking brake may be the same mechanism. The manual specifies a maximum turning radius of 13.1 metres.
Memory tip: Read the full rule, including its conditions and exceptions.

2 What braking systems does the manual require on a motorcycle?
- A rear brake only
- Independent systems acting on the front and rear wheels
- A front brake only
Show the answer
Answer B: Independent systems acting on the front and rear wheels
Steering must be in a condition that allows safe and efficient control. A motorcycle needs independent front and rear braking systems in working order. Light and heavy vehicles require working service, parking and emergency braking; the emergency and parking brake may be the same mechanism. The manual specifies a maximum turning radius of 13.1 metres.
Memory tip: Read the full rule, including its conditions and exceptions.

3 May the emergency and parking brake be the same mechanism?
- Yes, the manual permits this
- No, they must always be separate
- Only if there is no service brake
Show the answer
Answer A: Yes, the manual permits this

4 What maximum turning radius is specified in the manual?
- 50 metres
- 13.1 metres
- 30 metres
Show the answer
Answer B: 13.1 metres

5 How many independent braking systems must a motorcycle have to be ridden on a public road?
- Two
- One
- Three
Show the answer
Answer A: Two
A motorcycle needs two independent braking systems, one for the front wheel and one for the rear wheel(s).
Memory tip: Bike brakes: two, front and rear.

- On the front wheel
- On the engine only
- On the chain
Show the answer
Answer A: On the front wheel
