Summer driving advice
The high temperatures and busy holiday routes of summer put extra demands on both car and driver.
With a little planning and preparation though you should be able to reduce the risk of a breakdown and keep stress levels to a minimum

Summer Breakdowns
![]() |
High temperatures aggravate any existing damage to the rubber. Under-inflation adds to the problem causing friction and more heat which can prove too much for weak spots, causing punctures and blow-outs. |
![]() |
Check tyre condition and pressures, adjusting for extra load if appropriate. |
![]() |
High temperatures can aggravate cooling system problems too. Low coolant level, leaking hoses and broken electric cooling fans can all result in overheating and expensive damage. |
![]() |
If the fan's broken it will soon become apparent when you meet slow moving traffic and engine temperature soars. |
![]() |
Check the coolant reservoir level regularly |
![]() |
Look out for wet or white staining on coolant hoses |
![]() |
Check the fan by running the car to normal temperature and allowing the engine to idle for five to 10 minutes - the cooling fan should cut in automatically. |
Summer Fuel Saving
![]() |
If you have to carry luggage on the roof, use a roof box to reduce drag. Alternatively load luggage on a roof rack as low as possible and wrap tightly in plastic sheeting. |
![]() |
If you are staying in one place for your holiday, take the roof rack or box off when you get there - you'll save fuel on day trips. |
![]() |
Open windows cause extra drag. Try air vents first particularly on a motorway or highways. |
![]() |
Once air conditioning has cooled the inside of the car, you may be able to turn it down or off. |
![]() |
Don't start the air conditioning if doors or windows are open. |
![]() |
Increase tyre pressures if carrying extra passengers or heavy luggage (Check the handbook). |
![]() |
Using a windscreen shade and opening up the car as soon as you get back to it will help to cool the inside. Opening windows while you drive out of a car park will lower the inside temperature before you start the air conditioning. |
Fatigue
![]() |
Break a journey over 3 hours with a 20 minute break. On longer journeys, take a break every two hours or so |
![]() |
Frequent short stops (of at least 20 minutes) are better than one long stop |
![]() |
Remember that it's illegal to stop on the motorway hard shoulder, except in an emergency |
Glare
![]() |
Sun glare causes many accidents, particularly under clear skies at dawn or dusk. |
![]() |
Keep a clean and unscratched pair of sunglasses handy |
![]() |
Avoid lenses which darken in strong sunlight - the windscreen filters out UV light so the glasses will change only slowly. |
![]() |
Clean the windscreen regularly, inside and out, to remove smears, which will catch sunlight and impair vision. |
![]() |
Renew worn or damaged wiper blades will also help to improve vision |
