Footage captured on a dashboard camera shows the moment a teenager dangerously cycles into oncoming traffic.
The video shows a boy, who is not wearing a helmet, performing a wheelie and cycling down the middle of North Street in Worthing.
Several cars were forced to stop on the town centre dual carriageway to avoid the cyclist, as a friend watches on from the central reservation.
It was captured at around 2pm on Sunday, June 9.
Sussex Police issued a statement warning all road users to behave safely: "While we cannot comment without knowing the full circumstances, we would advise all road users to abide by the Highway Code – not just for their own safety, but for the safety of others too."
