In the shocking incident during the Tour of Flanders, a service car veered across the road clumsily, sending New Zealand's Jesse Sergent flying across the road.

Sergent, of Trek Factory Racing, was one of an eight-man break when he was clipped by the neutral Shimano service car with about 105km of the famous race remaining.

As a result of the nasty crash, Sergent was forced to retire from the race with what was suspected to be a broken collarbone.

The car was promptly ejected from the race. That's all so far.

Incredibly, there was another car-based collision later in the race.

The FDJ team car slowed to attend to one of their riders, Seb Chavanel, who had stopped at the side of the road but the Shimanno car ploughed into the back of Mark Madiot’s car which sent Chavanel sprawling.

It could have been a lot worse though.

The appalling scenes will have reminded many cycling fans of the 2011 Tour de France when a similar incident saw Juan Antonio Flecha hit the deck and send Johnny Hoogerland sprawling into a barbed wire fence.
