Height barriers.

Why barriers are there

Most campervan height barriers are not there to protect a low roof. They are there to keep high vehicles out, often to stop overnight stays or unauthorised encampments. Councils say so: Derbyshire Dales lists car parks with 2.1 m barriers that are unsuitable for smaller high-sided motor caravans, and several North Somerset car parks use 2.1 m barriers. So a barrier usually tells you two things: you will not fit, and the owner does not want you there overnight anyway.

Know your van height, properly

The height in the brochure or on your V5C is not always the height you are driving. Measure it yourself:

1. Park on flat, level ground with the tyres at normal pressure and the van loaded as you travel.
2. Find the highest point. On a converted van it is often a roof vent, an air conditioner, a solar panel, a roof rack, a roof box or a rooftop tent.
3. Lay a long straight edge or spirit level across that point and measure from the ground to its underside, keeping the tape vertical.
4. Add a margin for anything you sometimes carry up there, like a kayak.

Write it down in both metres and feet and inches, because UK signs can show either or both. The government's Know Your Traffic Signs guide shows the warning and prohibition signs for maximum height. Put the number where you can see it while driving. We keep ours on a sticker by the speedo.

Why your height changes

The number you measured is a snapshot. A few things push it up or down, and it is worth knowing which way:

• Load and suspension. An empty van sits higher than a fully loaded one. Measure as you travel, then remember that after you empty the water tank and eat the food, the van may rise a little.
• Tyres. Bigger or all-terrain tyres, or a lift kit, add height. If you change them, measure again.
• Roof kit added later. Every new vent, panel, aerial, satellite dish or rack is a new highest point. We re-measure after any roof job.
• The ground. A car park entrance on a slope, a speed bump just before the barrier or a dip in the road changes how much clearance you really have.

Width and length matter in car parks too. Bays are sized for cars, and some barriers restrict width as well as height. If your van overhangs a bay, it may not be allowed to park there, so look for any coach or motorhome bays on the council's car park page.

Reading height signs

There are two kinds of height sign you need to know, both shown in the government's Know Your Traffic Signs guide. A red circle with a height in it is a prohibition: vehicles over that height must not go past. A red triangle warning sign tells you there is a low structure ahead, usually a bridge, with its height. Car park barriers often carry their own sign with the height painted on the beam itself. When metric and imperial are both shown, use whichever matches the number on your dashboard sticker, so you are not converting in your head at a junction.

Signed heights are a guide, not a promise of clearance. Resurfacing can lower the gap, and a barrier can be knocked out of shape. Leave yourself a sensible margin rather than relying on the last few centimetres.

What you will meet

We are only giving figures we have seen published. Car park barriers at 2.1 m are used by councils including Derbyshire Dales and North Somerset, and by other landowners. Other heights exist, so read the figure on each sign rather than assuming. Low railway bridges are a separate risk: Network Rail reported 1,666 bridge strikes between 1 April 2024 and 31 March 2025, about one every five hours, and its advice is to know your vehicle's height, plan your route and watch for low bridge signs.

Habits that help

• Look before you turn in. Barriers are often set back from the entrance, after the point where it is easy to turn round. Look on street view or the car park's web page first.
• Check the council page. Many councils list which car parks have barriers and which have coach or motorhome bays.
• Use a sat nav or app that knows your height if you can, and still read the signs, which win.
• Do not trust "it'll be fine". If the van is within a few centimetres of the sign, the barrier may be lower than marked, and surfaces vary.
• Know where you are going to sleep. Many barriered car parks would not allow you overnight anyway; see our overnight parking rules.
• If you hit one, stop safely, check for damage to the roof fittings and seals, and report it to the car park owner. If you hit a bridge, stop and report it straight away so it can be checked before trains or traffic use it.

Choosing a van? Height is worth weighing up front; our best vans to convert guide covers the trade-off between standing room and fitting places.

Keep the numbers together

Alongside height, we keep the van's length, width and weight on the same sticker and in our phone notes. Weight matters for some bridges and roads, and for the Highway Code's parking lights rules, which treat vehicles over 2,500 kg laden weight differently. Having everything in one place means nobody in the passenger seat is searching the V5C at a junction.

Questions

What height are car park barriers in the UK?

There is no single standard. Many councils use 2.1 m barriers, but always read the sign at each car park.

Will a campervan fit under a 2.1 m barrier?

Some low vans and closed pop-tops might; most high-top conversions and motorhomes will not. Measure your van and compare.

Where do I find my van's height?

The manufacturer's spec gives a starting figure, but conversions add roof kit. Measure from the ground to the highest point on level ground.

Can I park in a car park with a height barrier?

Only if you fit under it. Some car parks have separate coach or motorhome areas outside the barrier; the council's car park page usually says.
