Overview

• Heatwave forecast to start Tuesday, June 17, prompting motoring experts to warn drivers of little-known safety regulations.
• Drivers should remove sunglasses once daylight fades since wearing dark-tinted lenses at night can obscure traffic lights and road markings.
• Operating a vehicle in flip-flops or Crocs breaches Rule 97 of the Highway Code and could incur a £100 fine or three penalty points if control is judged impaired.
• Drinking water is legal while driving but Rule 148 requires full control of the vehicle and motorists may need to stop to hydrate safely.
• Experts recommend keeping a spare pair of approved Category 2 or 3 sunglasses in the car to ensure proper eye protection throughout the day.
