Legal experts have warned drivers that taking certain antihistamines for hay fever during the current heatwave could result in a fine of up to £5,000. The warning comes as the UK experiences high pollen counts, prompting many to take medication for symptoms such as runny noses and watery eyes.
Drowsy Driving Breach
Markus Lindblad, Head of Legal and External Affairs at Haypp, explained that drowsiness is a common side effect of some antihistamines and that driving while drowsy is a breach of the law. He stated: "Hay fever season peaks in summer, but certain antihistamines cause severe drowsiness. If you drive after taking medication with a 'do not operate heavy machinery' warning, you risk fines of up to £5,000."
Sunglasses and Vision Restrictions
Drivers are also advised to be cautious with eyewear. While sunglasses are permitted, Category 4 lenses, which are heavily tinted, are too dark for driving. Lindblad added: "You can absolutely wear sunglasses while driving. However, avoid heavily tinted Category 4 lenses, which are too dark for driving." Wearing sunglasses at sunset or outside daylight hours could be considered restricting vision, leading to fines ranging from £1,000 to £2,500.
Anti-Idling and Footwear Rules
Motorists attempting to keep cool by leaving their engine running while stationary may face fines from local councils. Rule 123 of the Highway Code states that drivers must not leave a vehicle's engine running unnecessarily on a public road. Those idling to run air conditioning could be fined up to £110.
Footwear is another concern. While there is no specific ban on flip-flops, Rule 97 of the Highway Code requires that clothing and footwear do not prevent proper control of the vehicle. Lindblad noted: "If stopped by the police or involved in an incident due to poor footwear, you could be charged with an on-the-spot fine of £100 and 3 points on your licence. If the case goes to court, the penalty can escalate up to a £5,000 fine, 9 penalty points, and a potential driving ban."
