Emergency services responded to a collision involving a lorry and car on the anticlockwise carriageway.

The collision occurred at approximately 07:45 on a weekday, a time identified by the transport desk as peak traffic. The site of the crash lay on the northbound carriageway, a stretch that carries a high volume of commuter traffic into London. Emergency services arrived within minutes, confirming that both vehicles were involved in a single‑impact event.

Impact on commuters

With two lanes blocked, traffic controllers diverted vehicles onto the remaining carriageway. The resulting queue extended beyond the junction with the A1, according to live traffic monitors. Motorists reported travel times increasing by up to 45 minutes, and some drivers were forced to seek alternative routes via the A406 or local A roads.
