What happened

Five cars collided on the Udinsky Bridge in Ulan-Ude, and one of the vehicles caught fire after a heavy impact. The crash was reported by Radio 1 on 17 October 2026, based on footage from the scene published by the Telegram channel Babr Mash.

Eyewitnesses at the scene suggested that black ice on the bridge may have contributed to the pile-up. Ice can form on bridges before it appears on ordinary roads, because cold air circulates above and below the bridge deck, and a thin, near-invisible layer can catch drivers by surprise.

Police were working at the scene after the crash. Traffic on the bridge was disrupted, with drivers having to go around the wrecked vehicles. At the time of the report, information about possible casualties was still being clarified, and no confirmed injury or death toll had been released.

Why bridge pile-ups are so dangerous

A pile-up on a bridge leaves drivers with nowhere to go: there is no verge to escape onto, and vehicles behind the initial collision often cannot stop in time. When a vehicle catches fire, the risk grows further, and the need to keep the carriageway clear for emergency vehicles makes the disruption worse. Early-morning ice on bridges is one of the most common triggers for these chain collisions.

If you drive on routes like this

• Slow down before bridges and shaded stretches in cold weather — ice forms there first
• Leave a much larger gap than usual when the temperature is near freezing
• Brake gently and early on bridges; sudden braking on ice can start a skid
• Never assume the road is clear just because it looks dry — black ice is nearly invisible
• Know the local emergency number before you travel — our emergency numbers directory covers every country

What happens next

Police at the scene will establish the sequence of the collisions and whether ice, speed, or following distances played a part. Casualty figures, if any are confirmed, will be released by the authorities as the picture becomes clearer.
