Running dry happens more often in Cornwall than people expect. Filling stations are sparsely spaced once you leave the main towns, several close overnight, and holiday traffic means the drive you planned can take far longer than the range you had left.
The instinct is to walk to the nearest station. On a fast A-road that is genuinely dangerous, and it is rarely the quickest fix.
First, get safe
A car that has run out of fuel usually stops in a poor position, because it dies where the fuel does — often on an incline or mid-bend. Get as far left as possible while you still have momentum, hazards on.
On the A30, A38 or A39, get out through the nearside doors and stand behind the barrier or up the bank. Do not walk along the carriageway.
How a fuel drop works
Roadside assistance brings enough fuel to get you to a filling station and back on the move. It is a short visit, and for most petrol cars that is the end of it — put fuel in, start up, drive on.
It is normally quicker than walking to a station, buying a can, and walking back, and it does not involve carrying fuel along a live road.
Diesels need an extra step
Many diesels draw air into the fuel system when they run completely dry, and simply adding fuel does not always restart them. Some need bleeding or priming before they will fire.
If your diesel will not start after fuel is added, that is normal rather than a new fault — and it may need recovery to a garage instead of a roadside fix.
Avoiding it in Cornwall
Treat the west of the county and the north coast as lower-density for fuel, especially at night. If you are heading beyond Penzance, out onto the Lizard, or up the A39 towards Bude late in the day, filling before you go is worth the five minutes.
The same applies to the A30 west of Bodmin, where the gaps between stations are longer than most visitors expect.

Frequently asked questions
Should I walk to the nearest petrol station?
Not from a fast A-road. Walking along or crossing a live carriageway is far more dangerous than waiting, and a fuel drop is usually quicker anyway.
How much fuel do you bring?
Enough to get you to a filling station and refuel properly. It is a get-you-going measure, not a full tank.
My diesel will not start even after adding fuel. Why?
Diesels often draw air into the fuel system when run dry and need bleeding or priming before they restart. That is common, and if it will not start at the roadside the vehicle is recovered to a garage.
Can you help if I have run out on private land or a campsite?
Yes. Give us the site name and the access details and we can attend off the public road.
