Supermarket shoppers have been urged to be mindful when parking their car at sites across the country, after experts outline set ‘rules’ which should be followed. Specialists have argued drivers should always reverse into parking bays, with researchers at Nottingham University claiming one in five traffic collisions occur in car parks. Which? has also previously conducted an analysis on accidents at supermarkets, with the experts stating vehicles are twice as likely to suffer damage in a grocer’s car park than in a shopping centre car park. The organisation states: “When it comes to parking bays, you should be reverse parking. By that, we mean you should be reversing into your bay, so you can drive out forwards when you leave.

Good question. Let’s take a look: Discussing the frequency of car park incidents, experts described the percentage as “significant” given the minimal time spent manoeuvring in these areas. They emphasised that the issue extends beyond vehicle damage, with 15,000 people injured in America after being struck by reversing motorists – including 250 deaths, the Daily Record said. The guidance stated: “We’re not saying, ‘reverse park and you’ll never have another car accident again!’. It’s about reducing risks and creating a culture of safety. “But there are other benefits to reverse parking. For example, did you know it’s more fuel-efficient? “According to research from the Institute of Advanced Motorists, reversing out of a parking space with a cold engine uses up to 25 times more fuel in the first few seconds than a warm engine.

Reverse parking is basically better for everyone.” Mastering the art of parking in a driving bay is a “skill worth mastering”, warns the AA. Not only does it offer numerous benefits, but one in three learner drivers will also be required to perform this manoeuvre during their driving test. The motoring organisation has put together a beginner’s guide to bay parking. Here’s what they advise on reverse bay parking: “To park accurately, you want your car to be fully within the bay lines. Try not to stick out, or clip the kerb – or anything else. “You should also have good all-round observation at all times during the manoeuvre. You should be looking for potential hazards, such as pedestrians or other vehicles. “There might be a dog without a lead or a small child so you need to stay alert. If there are any road users nearby or approaching you, you should always stop to let them pass. Only continue with the manoeuvre when it’s safe to do so.” The AA advises: “We recommend reverse bay parking when you can, it is easier to make your observations and to see other road users. “In your driving test, you pick the bay that you will park in. Try to choose a space that will give you plenty of room for the manoeuvre. “We have outlined the steps for you to reverse park on the left side. If you reverse park on the right side just reverse the instructions.”
