How clear are you about the different types of child seats available?
The Highway Code can be confusing as we try to make sense of the table showing the heights, ages and weights relevant to seat belts and child restraints (see rules 99, 100 and 101 on line highway code)
Here is a link to Rospa's Child Car Seat information which you may find useful. Click on the view more videos link for information films.
When searching for information about using child restraints make sure you only use trusted sources such as the Highway Code and Rospa. If you do not want to use the above links search on line for the information.
