Police will be stopping cars across Hull with children on board to enforce compliance with child car seat safety legislation.
Officials say the purpose of this exercise is to inform and advise on correct seat fitting.
By law, children travelling in any vehicle must have the correct child car seat.
Correct fitting is determined by a combination of weight and height, and children must normally use a car seat until they're 12 years old or 135 centimetres tall, whichever comes first.
Last year it was found that nearly 8 of 10 seats were fitted incorrectly.
Councillor Mike Thompson, portfolio holder for neighbourhoods and communities said:
The Council regularly holds car seat clinics on the third Tuesday of every month between February to November.
- The next one will be held at Asda Kingswood on Tuesday 19 September, 10am to 3pm.
