A Nissan March automobile near the Wat Boonkanjanaram crossroads on Sukhumvit Road collided with a traffic barricade, forcing it to topple over and fall on its roof.
Jirat Phiphatkraibamrung, the driver, was only slightly hurt, but his female passenger was uninjured.
Jirat claimed to have hit the concrete obstacles at a high rate of speed because of the low visibility at night that prevented him from seeing them.
Police in Pattaya examined the accident site and gathered evidence. To pinpoint the precise reason for the collision, police will examine footage from closed-circuit cameras.
