How Which? tests baby car seats
Each car seat tested endures a front crash, equivalent to a head-on collision at around 40mph, and a side crash equivalent to two cars crashing at about 30mph, repeated again and again, in the different ways a car seat can be used.
We can go through as many as 20 samples of the same seat to get the final result.
Crash tests Our experts have specially designed the crash tests, making them more demanding than the legal minimum standard. They’re derived from Euro NCAP, which carries out crash testing on cars to show how well cars protect occupants in severe accidents. Our tests do a similar thing for baby car seats, as we feel this more accurately reflects what could happen in a real crash.
Crash-test dummies These are wired up to record the crash forces on the most vulnerable parts of the body and help to accurately indicate the risk of injury a real child could have in a crash.
Multi-group seats If a car seat can be used in a number of ways and attached by different methods (Isofix or a car’s seat belt) we crash test it in each format.
