Warm summer weekends and festivals are causes for celebration, but there are a couple of things drivers should bear in mind, as our guide details

With more than 100,000 people travelling to Glastonbury Festival by car this weekend 鈥 and with temperatures set to soar to the high twenties 鈥 carwow is warning revellers of the heat and fire risks to watch out for. Dangers include everything from hot exhausts brushing against long grass, to water bottles left in a parked car concentrating the sun鈥檚 rays to the point of ignition.

Avoid any summertime sadness and read our top festival tips for keeping your car safe, while you look good on the dance floor:

1. Don鈥檛 be a rocket man 鈥 watch out for exhaust ignition

Make sure if you鈥檙e driving to the festival, that you park in a designated area and avoid parking up on long grass that鈥檚 not an official parking spot.

Doing this in a petrol or diesel car presents risks, with car exhausts reaching 200掳C 鈥 easily hot enough to ignite grass if it鈥檚 tall enough to reach the exhaust. It鈥檚 also worth pointing out that brake discs can reach 500掳C after heavy use, so bear this in mind if you鈥檝e been driving in a spirited fashion. Festival traffic wardens will direct you to official parking spaces, while parking permits are available to purchase at the gates.

2. Oh, sweet tyre of mine!

It鈥檚 not just a car鈥檚 exhaust that poses a fire risk: if the ground is really dry, friction from a car鈥檚 tyres spinning on desiccated grass can be enough to create smouldering. The clue in the word 鈥榖urnout鈥 is likely to put people off deliberately spinning their wheels, but really dry grass is a low friction surface, so a gentle, cautious approach should be taken when moving off if you have to park on short grass.

3. Mirror, mirror on the dash 鈥 focus on reflections

Lizzo might blame it on the juice, but while car wing and rear-view mirrors tend to be convex and concave mirrors are the ones that can concentrate the sun鈥檚 rays to the point of ignition, other items found in the car can cause a fire if you get unlucky with solar angles.

There have been documented cases of child-monitoring mirrors attached to the back of headrests causing vehicle fires, while spectacles, water bottles and even shiny alloy wheels can focus the sun鈥檚 rays on a concentrated enough area to start a fire. Think about what you鈥檙e leaving in the car, where these items are placed and where you鈥檙e parking to minimise your risks.

4. Before you go 鈥 portable electronics pose risks, too

Think like Lewis Capaldi and, before you go, make sure you鈥檙e not leaving portable electronics in direct sunlight and instead take everything with you 鈥 even sat-navs.

Personal electronics typically come with warnings about maximum safe operating temperatures, and these are often around 32掳C or so. But car interiors can reach up to 60掳C in summer due to the greenhouse effect, and such highs not only pose a risk of damaging laptops, phones and the like, but also increase the dangers of batteries overheating and starting a fire. Placing these items out of direct sunlight in a glovebox or cubbyhole doesn鈥檛 overcome this, either, as such compartments can get almost as hot as the rest of the cabin.

Commenting on the warnings, carwow鈥檚 consumer editor, Hugo Griffiths, says:

鈥淢any drivers going to Glastonbury will be understandably excited for the festival and rush to leave their cars to set up their tents. But it鈥檚 easy enough to leave a pair of sunglasses on a dashboard top, or forget just how hot internal combustion engines get.

鈥淥f course, they say it changes when the sun goes down(!) and it does 鈥 it鈥檚 really the intense heat and sun that can cause some serious damage to parked cars. So it鈥檚 worth deploying just a little extra conscientiousness, having a quick look around and underneath your car before heading off on your festival adventures.鈥
