Picture the scene, because a lot of people lived it recently: a serious incident somewhere on the M25, the road closed in both directions, and thousands of drivers sitting in stationary traffic for the best part of eight hours. Engines off. Phones dying. Children in the back. Fuel gauges creeping down with the heating on. Night coming in. And nowhere — literally nowhere — to go.
That last part is the one worth sitting with. Not the delay itself, but the trapped. On a motorway, when the road ahead stops, so do you, and there is nothing you can do about it.
A motorway is a closed system
Motorways are engineering marvels, and they're built for exactly one thing: continuous, high-speed flow. Everything about them serves that goal. Junctions are spaced miles apart. There are no right turns, no crossroads, no legal U-turns. A central barrier stops you crossing to the other side. Fences and embankments seal off the edges.
All of that is brilliant when the traffic is moving. But it means a motorway has no release valve. The moment something serious blocks the carriageway ahead, everyone behind it becomes captive — held in place until the incident is cleared, however long that takes. You can't nip off at the next junction, because the next junction is four miles away and the four miles in between are a car park. You can't turn around. You just wait.
The problem was never that the motorway was moving too fast. It's that when it stopped, it took away every option you had.
To be fair to motorways
Here's the honest bit, because it matters. Motorways are not dangerous roads to drive. In fact they're the safest roads we have: per mile travelled, they have the lowest fatality rate of any road type in Britain, while quiet rural back roads actually have the highest. This isn't an argument that motorways will get you hurt.
It's an argument about a different kind of risk — the failure mode. Most roads fail gently. A motorway fails totally. When it goes wrong, it doesn't just slow you down; it removes your ability to make any decision at all. And eight hours with no fuel, no toilet, no way to reach a poorly relative or collect a child from school, is its own kind of unsafe — just one the safety statistics don't count.
The back road always has another way
Now picture the same blockage on a country road. A tree's down, or there's been a shunt, and the lane ahead is shut. What do you do? You turn around. You take the next turning. You cut through the village, ask at the pub, follow the little brown sign to somewhere you've never been. It might add twenty minutes. It might turn into a better evening than the one you'd planned.
That's the quiet trade the back roads offer. You give up the motorway's guaranteed speed, and in return you get guaranteed options. A B-road is a network, not a tube. There is always another way through, because the whole landscape is threaded with lanes that connect to other lanes. You are never really trapped.
Know the way before the signs turn red
None of this means swearing off motorways — they're the right tool for a lot of journeys. It means knowing the alternative. For the trips you make often, it's worth learning the parallel back-road route once, so that when the overhead gantry flashes "M25 CLOSED," you already know where to peel off. That's exactly what brieflylost is for: it plans routes along country lanes and B-roads instead of motorways, so the back way stops being a mystery. If you want to see how that compares to the usual apps, here's brieflylost vs Google Maps, Waze and the rest.
The long way is also the free way
There's a version of this that isn't about emergencies at all. The back road is where the drive actually happens — the reason our complete guide to UK scenic drives exists in the first place. But the M25 is a useful reminder that the case for knowing the quiet roads isn't only romantic. Sometimes the long way round is the only way home. It's worth knowing it before you need it.
Frequently asked questions
Are motorways more dangerous than back roads?
Not in terms of crashes. Per mile driven, motorways have the lowest fatality rate of any road type in the UK, while rural back roads have the highest. The particular risk with motorways isn't a collision — it's that when one closes, it traps you, with no exit and no way to turn around.
Why do motorway closures strand drivers for so long?
A motorway is a closed system built for continuous flow: junctions miles apart, no U-turns, and barriers preventing crossing. When a serious incident blocks the road ahead, everyone behind is held in place until it's cleared — there's no release valve, which is how people end up stationary for hours.
How do back roads help if there's an accident ahead?
On a country road or B-road there's almost always another way through. If the road ahead is blocked you can turn around, take the next turning, or reroute through a village. You trade guaranteed speed for guaranteed options — you're rarely, if ever, truly trapped.
Can a route planner avoid motorways in the UK?
Yes. Google Maps and Waze have an "avoid motorways" setting, but it tends to keep you on large A-roads. brieflylost is built to plan routes along country lanes and B-roads, so you learn the back-road alternatives to the journeys you make often — useful to know before the signs turn red.
