Two fire crews from Middlemoor and Topsham were called out following a collision involving three cars in Countess Wear, Exeter.
Initial reports from police indicated there had been a fuel spillage on both carriageways.
The firefighters from Middlemoor made the vehicles safe and their Topsham colleagues were not required at the incident, which happened in Bridge Road shortly after 2.30pm on Sunday.
Drivers were advised to avoid the area as severe tailbacks built up on the Countess Wear roundabout and surrounding roads.
All vehicles were made safe and the scene was left in the hands of the police.
