Drivers have been warned about height restriction rules that will impact people using the car parks of UK supermarkets such as Aldi , Asda , Sainsbury’s, and Morrisons . These chains could enforce strict height rules to stop certain vehicles from entering with a barrier of around 2m, according to experts at StartRescue . This would impact the 500,000 HGVs registered in the country, all of which would be blocked from the locations.

Some car parks may have height restrictions based on ceiling/roof height – if applicable.” “High-sided vehicles can cause congestion in car parks of all types. “For this reason, such vehicles may be restricted by a barrier with a horizontal bar at the maximum height.” It comes as millions of motorists, road users and drivers are vowing to never buy an electric car despite an incoming ban on petrol and diesel vehicles. Some drivers are already making use of the £650 million Electric Car Grant to buy a new EV. Drivers are not yet being given the conditions that would enable most to switch to an electric vehicle (EV), according to research. Factors such as upfront costs and access to charging are among significant barriers to “mass adoption” of the technology, the AA said. The AA has launched an “EV readiness index” aimed at reflecting how practical and appealing EV ownership is. Edmund King, AA president, described the recently introduced electric car grant – which reduces the cost of some new EVs by up to £3,750 – as a “welcome boost” but warned “we need to go further to make EVs a realistic choice for all drivers”. He said: “Drivers tell us they’re excited about going electric and they love the tech, but they’re also confused and cautious. “Our index shows that upfront costs and charging access are still major concerns. Our polling also suggests battery health and resale values are still issues for some. “Our index is an independent barometer of the issues that are either holding drivers back or propelling drivers to go electric. We are confident that the readiness rating will increase with more chargers, less expensive products, targeted incentives and better information.”
