Top 10 Child Car Seat Safety Tips

1. Maximum safety

Some parents move their child up to the next stage car seat as soon as they are ‘big’ enough, not realising that it is a big step down in child car seat safety.

Keep your child in the lower stage car seat until fully outgrown by weight or height.  


2. Escape artists

It can be extremely frustrating when your child learns that they can slip their arms out of the harness like Houdini and it is also very dangerous!

There are a number of thing’s you can do to stop your child escaping from their harness:

3. Harness height

The correct height of the harness can be confusing.

  • If a seat is REAR FACING the harness should be level with or just BELOW the child’s shoulders.
  • If a seat is FORWARD FACING the harness should be level with or just ABOVE the child’s shoulders

4. Harness tension

Many of the seats we check at our free community events find the harnesses are too loose, however the good news is it’s an easy issue to fix.

Harnesses should be tight enough on your child so you can only get two fingers between the child and the harness – with your fingers lying flat against the child’s collar bone.  

Alternatively, you can do the ‘pinch test’. First, place your fingers on the harness, around the child's collarbone area. Then try to pinch the harness strap and if you can get a good pinch between your fingers, that means the harness is not tight enough.

When you take your child out of their seat, loosen the harness off before you unclip the buckle – that way, when they next go into their seat, you just need to pull the harness tensioner to get the perfect fit.

5. Car seat clothing

Children should travel lightly dressed when in the car; ideally the kind of clothes they would be wearing when playing indoors.  In very cold weather, it’s a good idea to warm your car up first and certainly wrap them up when taking them to the car. Once you have put your child in their seat, all puffy and thick jackets must be removed.  You can keep your child warm with a blanket placed over the top of them once safely fitted into the seat. Babies should also be lightly dressed then a blanket wrapped tightly around them once their harness is secured and tensioned.

6. Wobbly seats

A very common mistake is the seat belt not being pulled tight enough when the child seat is fitted.  The child restraint should not wobble or move more than 1 inch.  If you have pulled the belt as tight as possible and the seat still moves about, it is possible it is not fitted correctly or compatible with your vehicle.

7. Getting the right fit

Child seats have blue guides if they may be used rear facing, and red guides if they may be used forward facing.  Make absolutely sure the seat belt passes through the correct guides – it doesn’t necessarily go through every guide! R129 belted seats have green guides.

8. Using the back on a booster

Booster seats should be used with the back support in place as long as possible – head rests on a majority of high back boosters will raise up to accommodate your growing child.

9. Buckle crunch:

The plastic casing of the seat belt buckle should not sit on or over the frame of the child seat; if it does, it may not hold in an impact.

10. Most important child car seat safety tip

Not every seat fits every car.  Whether seat belt or ISOFIX, it is essential to ensure your vehicle and child's car seat are compatible and that the seat fits correctly.  If a seat is not fitted correctly it will not be able to protect your child properly in an impact. Always check both your vehicle handbook and child seat manual first.

I-size seats (part of ECE R129) are designed to make travelling with your child even safer as they are guaranteed to fit any i-Size seating position in an i-Size compliant car. You still need to ensure your child fits safely into their seat however.

The hidden projectile in your car - Booster seats

The hidden projectile in your car - Booster seats


When children are younger, they use a child car seat that contains a harness to restrain them. This seat is fitted into the car, where it normally stays strapped in, so even when your little one is not in the car, their seat remains restrained.




The next stage seat - boosters

When it comes to your child moving up to a booster seat, both the seat and the child are restrained with the adult seat belt.




This means that unless you buy an ISOFIX booster seat, you need to remember to strap the booster in when not in use.



An unrestrained booster will multiply its weight by the force of a collision, so if you have a crash when your child is not in the car, but their booster is sat on the back seat - you have a very heavy projectile waiting to hit someone!


Spot the Error!


Spot the error! Take the above child seat, the Britax Adventure. This seat is known for being lightweight and portable, so it is easy to move between vehicle's. This child seat weighs just 3.9kg. In a 30mph collision, the seats weight will be multiplied, and when the seat flies forward, it will hit whatever it impacts with a weight of 117kg - or 18.4 stone! If you have a little one sat next to the seat that is flying around, or a passenger in the front, or even if the seat is behind you as a driver - 18 stone hitting the back of the seat, or a person is not good news! So for the safety of all, remember to strap in your non ISOFIX booster seat!


ISOFIX Boosters


KIDFIX_II - edited


ISOFIX boosters don't need to be strapped in when your little one is not in the car, because the ISOFIX provides a rigid attachment to the vehicle. Just one of the great benefits of ISOFIX! Both ISOFIX and non-ISOFIX booster seats offer great protection for a child, but remember to strap in the non-ISOFIX booster when your child isn't out and about with you!
