Firefighters battled to douse the flames from two blazing cars on Royal Windsor Way (formerly Windsor Eton Relief Road) yesterday evening.
The two vehicles - a Volkswagen Golf and a Seat Leon - burst into flames after being involved in an accident at 6.15pm.
The drivers and passengers were safely out of the cars by the time the fire service arrived. But the key link road was closed for an hour while the flames were put out.
Two pumps, two breathing apparatus and two hosereels were used.
