Even though the hot summer months are behind us, leaving a child or pet locked in a vehicle is still dangerous. In autumn, the weather can be unpredictable, sunny days can still cause temperatures to climb inside a car, while cold snaps can put children and animals at risk of hypothermia. At Carsmith Midlands, we know how quickly situations can escalate, which is why knowing what to do can make all the difference.
Cars heat up and cool down faster than you think
In warmer autumn weather, a car’s interior can still rise by 10–20 °C within minutes, even if it doesn’t feel hot outside. On cooler days, the opposite is true: vehicles can become dangerously cold in a short amount of time, especially for young children, pets, or the elderly. Either way, being locked in a car can quickly become a medical emergency.
Immediate steps to take
- Call emergency services right away
Whether you’re the driver or a bystander, dial 999 (in the UK) immediately if a child or pet is locked inside a vehicle. Stress the urgency – autumn weather extremes can harm just as quickly as summer heat. - Try to locate the keys or unlock the car quickly
If a spare key is nearby or someone can access the vehicle safely, do so immediately. But don’t waste time if this isn’t possible. - Stay with the vehicle and monitor the situation
Stay close to reassure the child or pet, and keep an eye on their condition while waiting for help. - Break a window only if absolutely necessary
If emergency services can’t arrive quickly enough and the situation is critical, breaking a window may be legally justifiable. Choose the window farthest from the child or pet and take care to avoid injury.
Why autumn still brings risks
- Sunny days – Even mild autumn sun can turn a parked car into an oven.
- Cold snaps – Pets and children can suffer from hypothermia if trapped in a cold vehicle.
- Shorter daylight hours – Emergencies can happen in the dark, making it harder for others to spot someone locked inside.
Preventing these emergencies
- Never leave children or pets unattended in a car, even for a few minutes.
- Always check the back seat before locking your car.
- Keep keys out of reach of children and avoid leaving them inside the vehicle.
- Use reminders such as phone alarms or placing essential items in the back seat.
- Consider safety devices like seat alarms or temperature monitors.
