Did you know that 4 out of 5 car seats are improperly installed? These are the most common mistakes:

  • Car seat is not right for the child’s weight and height.
  • Vehicle seat belt is not tight enough to secure car seat properly.
  • Harness or shoulder straps are too loose.
  • Tether strap is not used or used incorrectly.
  • Locking clip is not used when required.

Types of Car Seats

Each type of car seat is different! Choose one that is right for your child’s weight and height, and has the National Safety Mark label attached to the seat (round sticker with maple leaf).

Use infant-only car seats from birth to 10 kg (22 lbs).

  • Keep rear-facing for as long as possible – to maximum height/weight limit of your car seat.
  • Always place in the back seat, rear-facing, at 45 degree angle.
  • Base of car seat attaches and is anchored properly to the vehicle seat.
  • Pull anchoring belt tight so that the car seat moves no more than 2.5 cm (1 inch) forward or sideways.
  • Harness straps must lay flat and snug so no excess strap can be pinched at the collarbone. Harness straps must be at or slightly below the shoulder.
  • Move chest clip to armpit level.
  • Place carrying handle in position recommended by manufacturer.

Infant/child car seats can be used as a rear-facing or forward facing car seat.

  • UAS system only works for children up to 40 lbs. Use the seat belt for children over 40 lbs.
