What is the maximum width permitted for a bus or coach in the UK?
Answer: 2.55 metres
The maximum permitted width for a bus or coach in the UK is 2.55 metres (approximately 8 feet 4 inches). This limit ensures vehicles can safely navigate standard road widths and pass oncoming traffic.
What is the maximum overall length of a single-decker rigid bus in the UK?
Answer: 12 metres
The maximum overall length for a single-decker rigid bus is 12 metres. Articulated (bendy) buses may be longer, up to 18.75 metres, but standard rigid buses must not exceed 12 metres.
Why is it important to know the unladen weight of your PCV?
Answer: To determine the maximum number of passengers you can carry
Knowing the unladen weight allows you to calculate how much payload (passengers and luggage) you can carry before reaching the maximum gross vehicle weight. This prevents overloading.
What is the maximum permitted height for a double-decker bus in the UK?
Answer: 4.57 metres
The maximum permitted height for a double-decker bus in the UK is 4.57 metres (approximately 15 feet). Drivers must know their vehicle's exact height and be alert for low bridges.
How does exceeding the maximum axle weight affect a PCV?
Answer: It can cause tyre failure and premature suspension wear
Exceeding maximum axle weight can cause tyre failure due to excessive loading, premature wear of suspension components, and reduced braking efficiency on that axle. It also causes accelerated road surface damage.
What is the standard weight allowance per standing passenger used when calculating PCV loads in the UK?
Answer: 63.5 kg
The standard weight allowance per passenger in UK PCV calculations is 63.5 kg (approximately 10 stone). This figure is used to calculate total passenger load against the vehicle's weight limits.
