A taxi driver caused a horrific crash at the Tour of Costa Rica yesterday when he turned across the front of the speeding peloton, with several riders slamming into the vehicle.

The incident was caught by a spectator on a video uploaded to Twitter. It shows how, once the lead vehicles and front riders passed, the driver spotted a gap and tried to execute a left turn with disastrous consequences as the peloton arrived.

The crash happened in Alajeula during the opening day of the 11-day race, reports the Tico Times, which says that afterwards, a number of the riders confronted the driver, Wilberth Arce, with some of them kicking the taxi.

The motorist says he wasn’t to blame, however, and claims that race officials told him to turn left to get off the road.

“I’m out here trying to make an honourable salary and the cyclists are the ones who acted out with vandalism when they began to kick my car,” he explained.

The worst hurt rider was Felix Aroyo of the Star Cars BCT team, although he was able to complete the stage after receiving medical attention, according to a report in La Nacion.

In a statement on Facebook, race organisers confirmed that legal action would be taken against the taxi driver.
