New laws for child seats in cars come into effect today, but police will be taking a discretionary approach while parents get to grips with the rules.
From today, the mandatory use of child restraints in vehicles will be extended by two years, requiring all children to be correctly secured in an approved restraint until their seventh birthday.
If an approved restraint is available in the vehicle, it must be used until children turn 8.
Approved child restraints include baby capsules, car seats and booster seats.
A police national headquarters spokesman said the rules would help to keep more children safe on the road.
