A lorry driver who falls asleep at the wheel swerves across a busy motorway, prompting police to intercept his vehicle, according to reports. The driver’s lorry drifts across lanes as traffic continues, creating a potential hazard for other road users. Police stop the vehicle after observing the swerving and intervene to prevent further danger. The incident is described as beginning when the driver appears to have fallen asleep while driving and then losing control enough to cause the lorry to cross the roadway lanes. The reports indicate that the driver is located and stopped by officers following the swerving. Details beyond the interception, such as the driver’s condition, any injury to other road users, or the exact location and time, are not provided in the supplied text. Overall, the accounts agree that fatigue is the reported cause and that police respond promptly after the lorry begins drifting across a busy motorway.
