A jeep hit a truck near the 81km mark of the Trakia motorway, in the lane towards Burgas, said Miroslav Stoyanov, spokesman for the Pazardzhik regional police (ODMVR). No one died.

The jeep driver suffered scrapes and cuts. Stoyanov said the likely cause was that the truck slowed down and the jeep drove into its rear.

Repairs are under way on this stretch, and signs set a lower speed limit. Cars heading to Burgas can use only one lane.

A day earlier, two pile-up crashes on the same motorway killed 12 people and injured 51 others with various injuries.
