Whether you live here or are visiting from abroad, hiring a car in the UK is the perfect way to see the world – and, for the most part, the roads of Britain are kind to drivers. Smooth tarmac, flowing traffic and not a pothole in sight. But some roads aren’t quite so forgiving.
With plenty of experience in car hire and short-term leasing, it’s safe to say we’ve come to know the UK roads well – which is why, with a little help from recent research, we’ve put together a list of five motorways to avoid if you’re driving in the UK – if you can.
So, let’s dive into some of the motorways and roads you might want to steer clear of when hiring a car in the UK.
M42
The M42 serves much of the Greater Birmingham area – and with a population of more than two million, that’s probably why so many people look unfavourably on this motorway.
Aside from the daily incidents, the M42 has had its fair share of roadworks in an attempt to improve the stretch – all of which contributes to long delays. But the real issue for most drivers is the road surface, with potholes being a major complaint.
Tip: If you’re hiring a car in the UK and you do have to travel on the M42, drive within regulations and leave plenty of time – just in case of delays.

M4
The M4 runs from West London all the way into Wales and – as you’d expect from Britain’s third-largest motorway – it gets pretty busy. Because of this, journey times are often delayed depending on where you’re going and how far you’re travelling.
With many UK drivers reporting feeling unsafe on the road, major roadworks are well underway to improve both safety and overall journeys along this motorway.
Tip: Again, if you are hiring a car in the UK and the M4 is on your route we’d always recommend leaving plenty of time – and checking current roadworks and their effect on your route.
M25
Considering that it circles the capital, the 117-mile stretch of the M25 sees around 200,000 vehicles daily – sparking heavy congestion, made worse by deteriorating road surfaces. So, if you’re driving a premium vehicle you may want to think twice.
Smart motorway sections and ongoing roadworks add to the frustration and safety concerns – but, in the long run, these upgrades will hopefully improve safety and reliability on this vital route.
Tip: Whether you’re a local or a tourist, driving on the M25 can be stressful. Pay close attention to lanes and junctions – they can change quickly – and stick firmly to the speed limit. Others may be racing to their destination, but you can take it slow and steady.
M27
The M27 may be one of the shorter motorways, but you should never underestimate a motorway. Journey times can vary drastically, and according to many UK drivers, the road surface isn’t up to scratch.
During heavy rain, the road – like many in Britain – is prone to surface water issues, meaning drivers should be especially cautious in adverse weather.
Tip: If you’re visiting Southampton or Portsmouth, using the M27 may be unavoidable – but don’t panic. This motorway can be absolutely fine. Just leave plenty of time and be sure to check the weather and traffic conditions before you head out.

M1
If you’re used to driving in Britain – whether that’s hiring a car, driving your own or touring via public transport – it may come as no surprise that the M1 features on our list of roads to avoid.
As one of the longest and busiest motorways in Britain, the M1 has a bad reputation – and probably for good reason. Roadworks are ongoing, the surface is far from ideal in places, and the biggest let-down is often journey times. But with 130,000 to 140,000 daily users, is that really a surprise?
Tip: While the M1 can be a headache for many drivers, it’s also a surefire way to move up and down the country. If you do choose to travel on it, take plenty of breaks – and don’t forget to enjoy the views the motorway has to offer.
Further tips for drivers hiring a car in the UK
Here are a few more useful tips for anyone hiring a car in the UK:
- EV chargers: If you’re lucky enough to be driving an EV, check charging points before you set off – not every service station has them.
- Petrol stations: If you’re driving a petrol or diesel vehicle, plan where you might need to fill up along the way. It’s easy to get caught in traffic without a petrol station for miles.
- Rest stops: Driving can be tiring, so plan when you’ll stop. If you feel tired, take a break – even a short one helps.
- Understand the rules of the road: Even experienced drivers can get confused. Take time to get to grips with any UK road rules or signs you’re unfamiliar with.
Of course, we could go on – but the most important tip is to enjoy yourself. Hiring a car is a fantastic way to see Britain, so make the most of the freedom it gives you.
