**Car Seats & Child-Passenger Safety**

Car Seats for Children are Compulsory

---

**Why this matters**

A properly fitted child seat cuts serious-injury risk by around 70 per cent. For children who have lived through trauma, clear explanations, predictable routines and the right restraint can also feel like a concrete promise of safety.

**What the law requires (England, Wales & Scotland)**

- **Under 12 years or under 135 cm** – a suitable child-car seat **must** be used on every journey.
- **12 years or 135 cm+ (whichever comes first)** – use the adult belt if one is fitted.
- **Driver responsibility** – you are legally liable for passengers up to their 14th birthday. ([gov.uk](https://www.gov.uk/child-car-seats-the-rules?utm_source=chatgpt.com), [gov.uk](https://www.gov.uk/seat-belts-law?utm_source=chatgpt.com))

**Three narrow exemptions** (when no seat is available):

1. Licensed taxi/minicab.
2. Unexpected, necessary, short emergency journey.
3. No room for a third child seat across the rear bench (child aged 3 + must still sit in back and use the adult belt).
   Children under three can **never** travel unrestrained except in exemption 1. ([gov.uk](https://www.gov.uk/seat-belts-law?utm_source=chatgpt.com))

**Seat categories – weight *or* height**

Regulation R44 (weight-based, still legal)

- Group 0+ · Birth–13 kg: rear-facing carrier.
- Group 1 · 9–18 kg: forward- or rear-facing harness seat.
- Group 2 · 15–25 kg: high-back booster.
- Group 3 · 22–36 kg: high-back booster or (see below) backless cushion.

Regulation R129 *i-Size* (height-based, current standard)

- Birth–83 cm: rear-facing i-Size.
- 61–105 cm: rear-facing or forward (after 15 m).
- 100–150 cm: high-back booster, usually ISOFIX compatible.

**Backless booster cushions** – new models may be used **only** for children over **125 cm and 22 kg** (rule introduced 2017). High-back boosters give better side-impact protection and are recommended for anyone under 150 cm. ([gov.uk](https://www.gov.uk/government/news/new-child-car-seat-rules-no-change-for-existing-booster-seats?utm_source=chatgpt.com))

**Choosing & fitting a seat – quick reminders**

- Follow the seat maker’s stated weight/height range and fitting instructions every time.
- When fitting in the front, **deactivate airbags** for rear-facing seats.
- ISOFIX or i-Size anchor points remove most fitting errors—use them whenever the car allows.
- Local Road-Safety Units (find them on your county council website) will check fittings for free; worth booking when a placement starts.
- Replace any seat involved in a collision, even a low-speed bump.

**Trauma-informed buckle-up tips**

- **Explain, don’t insist:** “The belt keeps every part of your body safe if we need to stop suddenly.”
- **Offer choice:** Which side of the car? Which soft toy rides too?
- **Sensory aids:** Belt-covers, weighted lap pads, noise-cancelling headphones can calm seat-belt anxiety.
- **Praise the positive:** Notice every smooth buckle-up—“I really appreciate how quickly you clicked in.”

If a child continually unbuckles or refuses, log each episode, alert your Supervising Social Worker and update the Risk Assessment so you can agree a graded desensitisation plan.

---

**Recording & escalation**

- Log any seat-belt breach or exemption in the Daily Record **same day**; complete an Incident Form if refusal is persistent.
- Note seat make/model and fitting check at the start of every placement.
- Crash, damage or seat failure? – replace the restraint, note the incident and contact the agency about insurance. The Health & Safety Policy requires the car-seat check at every unannounced visit.
