M40 Travel Tips
The M40 is a vital connection from London to Birmingham. Good planning can help you avoid delays and travel more safely.
- Avoid peak times when possible. Traffic is busiest on weekdays between 7–9am and 4–6:30pm, especially near the M25 and Birmingham.
- Pay attention to speed limits. The M40 has fixed and average speed cameras, and limits may change due to roadworks.
- Plan service stops ahead. There are few service stations, with Beaconsfield Services being the main one and often very busy.
- Check traffic updates before setting off. Accidents or lane closures can quickly cause delays.
