Car seats in India: the law, the types, and installing one properly

What the law says

The Motor Vehicles (Amendment) Act made child restraints and helmets for children a legal requirement, with rules requiring children under four on a two-wheeler to wear a helmet and be secured with a safety harness, and a speed limit of 40 km/h for that journey.

Enforcement is patchy, and the physics is not. Whatever the traffic police do or do not check, an unrestrained child in a collision at city speeds is the injury that fills paediatric emergency rooms.

For cars, use a rear-facing infant seat from the first journey home from hospital, and never place a rear-facing seat in front of an active airbag.

Choosing by stage

Infant seat, rear-facing, birth to about 12-15 months or until the child outgrows the height or weight limit: the safest configuration there is, because it spreads crash forces across the whole back and supports the head and neck.

Convertible seat: rear-facing as long as possible — many now allow rear-facing to two years or beyond, and every extra month rear-facing is a genuine safety gain — then forward-facing with a five-point harness.

Booster seat from around four years and 15-18 kg, until the adult belt fits properly: the lap belt low across the hips, the shoulder belt across the collarbone rather than the neck. Most children need a booster until around ten to twelve years.

Buy new where possible, check for a recognised safety certification, and never use a seat that has been in a crash or whose history you do not know.

Installing it right

The commonest mistakes: a loose base (it should not move more than about 2.5 cm side to side at the belt path), a harness that is too loose (you should not be able to pinch a fold of webbing at the shoulder), the chest clip too low (it belongs at armpit level), and bulky winter clothing under the harness, which leaves dangerous slack in a crash.

Rear-facing seats need the correct recline angle so a newborn's head does not fall forward — most seats have an indicator line.

The back seat is the safest place for every child under thirteen. If your car has ISOFIX anchors, use them; otherwise thread the seat belt exactly as the manual shows.

Read the manual, and if possible have the fit checked by someone who has installed one before. A correctly fitted average seat beats a badly fitted expensive one.

When to see a doctor

After any crash, however minor, a child should be assessed if they have any pain, drowsiness, vomiting, marks from the harness, or a head impact — and any loss of consciousness, repeated vomiting, unequal pupils or fluid from the nose or ears is an emergency, 108.

Also: babies should not sleep for long periods in a car seat outside the car, because the semi-upright position can compromise breathing in newborns. Move a sleeping baby to a flat surface when you arrive.
