INTRODUCTION
If you operate a long van, trailer, recovery truck, or commercial vehicle in the UK, here’s the uncomfortable truth:
You could be breaking the law without even knowing it.
Many drivers assume a “Long Vehicle” sign is optional. It’s not in certain situations, it’s legally required.
And here’s the twist
Failing to comply doesn’t just risk a fine. It could invalidate insurance and expose your business to liability.
Let’s break down the exact long vehicle sign requirements in the UK clearly, simply, and without the confusing legal jargon.
What Is a Long Vehicle Sign?
A long vehicle sign is a rear-facing warning sign displayed on vehicles that exceed certain length limits.
It typically reads:
- “LONG VEHICLE”
- “LONG LOAD”
- “LONG VEHICLE – DO NOT OVERTAKE TURNING”
These signs are designed to warn other road users that:
- The vehicle has extended length
- It may swing wide when turning
- Overtaking could be dangerous
They are especially common on:
- Articulated lorries
- Car transporters
- Recovery vehicles
- Vehicles towing long trailers
Key Questions People Ask
❓ Do I legally need a long vehicle sign in the UK?
Yes, if your vehicle exceeds standard length limits or carries an overhanging load.
Under UK road regulations:
- Vehicles over 13 metres often require rear marking
- Abnormal loads require proper signage
- Trailers with long overhangs must display warnings
Enforcement is typically monitored by the Driver and Vehicle Standards Agency (DVSA).
❓ What size should a long vehicle sign be?
While exact size depends on vehicle type, general guidelines include:
- Clearly visible from a safe distance
- Reflective material (especially for night driving)
- Positioned centrally or symmetrically
For commercial vehicles operating under safety schemes, signage may need to comply with Department for Transport guidelines.
❓ Does the sign need to be reflective?
In most professional fleet or heavy goods vehicle scenarios yes.
Reflective or high-visibility signage improves safety and reduces liability risk.
Many operators follow visibility standards aligned with the Health and Safety Executive (HSE) recommendations for workplace transport safety.
❓ What happens if you don’t display one?
Potential consequences:
- Fixed penalty fines
- Points on licence (in certain cases)
- Vehicle prohibition notice
- Insurance complications after accidents
Loss aversion matters here.
A £30–£100 sign could prevent thousands in penalties or legal issues.

How to Choose the Right Long Vehicle Sign
Before purchasing, ask:
- Does my vehicle exceed 13m?
- Do I carry loads that overhang?
- Is my sign reflective and durable?
- Does it comply with UK transport guidance?
If you operate a fleet, standardising signage across vehicles builds familiarity and familiarity builds trust.
And remember:
If you delay upgrading compliance signage, your competitor might already be ahead operating safer and appearing more professional.
Before vs After
