Matthew Briggs, the CEO of Right Fuel Card, explained that as the summer is the busiest period on UK roads, serious accidents occur at a far higher rate than throughout the rest of the year.
HGV drivers play a critical role in food and drink supply chains, which can also become stretched during periods of the year when demand increases, such as the summer.
“While it is important to practice safe driving all year round, it’s important for HGV drivers to have an increased sense of awareness, particularly when drivers on the road are not used to travelling long distances,” Briggs said.
According to data cited by Right Fuel Card, HGV drivers can work up to 56 hours a week, meaning that many are also at risk of health-related issues such as dehydration and fatigue because of higher temperatures during the summer.
This is particularly prevalent in cities and urban areas, which became hotter than rural areas because of the presence of taller buildings and narrow streets which block wind and trap heat.
“These factors lead to a temperature increase of between 3C and 6C during the day,” Briggs continued.
“HGV drivers are particularly affected by this, as long stops in traffic or dense city centres can lead to the cab’s temperature increasing rapidly, especially if the air conditioning is not effective or fails.”
Hotter conditions also increase the risk of mechanical issues, often the result of the engine overheating.
“HGV engines already work hard, and a long period of high temperatures can push the cooling system over the edge,” Briggs added.
“Additionally, if the coolant levels are low or the radiator is clogged, they may begin to steam from the bonnet mid-route. To avoid this, regularly check the coolant levels, fan belts and radiator.”
Dr Deborah Lee, from Dr Fox Online Pharmacy, offered further insight into the increased health risks that HGV drivers face during the summer months.
“Fatigue and dehydration are two of the greatest dangers for any driver,” Lee said.
“They often occur together, and either one or both can kill. 68% of road accidents are due to driver error, which can be caused by dehydration and fatigue.
“Although many drivers may not realise it, dehydration is a cause of fatigue. In a study by Loughborough University, drivers suffering from dehydration were found to commit as many driving errors as those driving under the influence of alcohol.”
To combat this, Lee advised that drivers drink plenty of water during long journeys, in addition to applying sun cream.
Concluding, Briggs said: “Driving an HGV in extreme heat is no small task – it’s physically and mentally demanding in ways many don’t see. Long hours on the road, sun glare, hot cabs, and the added strain on vehicles all combine to make summer one of the toughest times of year for our drivers.
“It’s not just about comfort; it’s about concentration, safety, and endurance.”
In related news, the number of HGV drivers employed in the UK increased by 13% year-on-year during Q4 of 2024.
