Bank holiday weekends are the most predictably chaotic times on UK roads. With millions of families travelling simultaneously, motorway journey times can triple or worse.

Easter Good Friday (18 April) and August Bank Holiday (22–25 August) are the two busiest traffic periods. The August Bank Holiday is historically the single worst weekend of the entire year. If you must travel on these dates, leave before 7am or after 8pm.

Peak Traffic Hours on Bank Holidays
Knowing when congestion peaks can make the difference between a smooth journey and a 3-hour standstill. Here's when traffic typically builds on each part of the weekend:
| Day / Window | Peak Hours | Traffic Type | Best Alternative |
|---|---|---|---|
| Friday (getaway) | 1pm–8pm | Holiday outbound; school finishes | Leave before 7am or after 8pm |
| Saturday morning | 10am–2pm | Day-trippers; late getaway | Leave before 8am |
| Sunday afternoon | 2pm–7pm | Early returners + day-trippers | Leave before noon or stay overnight |
| Monday (return) | 1pm–8pm | Main return wave; panic departures | Leave before 10am or after 8pm |
| Monday evening (return) | 5pm–9pm | Second wave; evening departures | By 9pm roads usually clear significantly |
Busiest UK Motorways on Bank Holidays
Not all motorways suffer equally. These routes are the most reliably congested on major bank holiday weekends:
Every junction becomes a pinch point. The Dartford Crossing area (J2 and J31) is worst — allow 60–90 extra minutes
The free M6 through Birmingham is stationary for hours. Use the M6 Toll (£7.40) to bypass this section
Devon and Cornwall holiday traffic. Friday afternoon in summer can mean 3+ hours of delays near Taunton
North-bound holiday traffic clogs the central section. Worst on Easter and August Bank Holiday
Wales and west country traffic. Severn Crossing now free but M4 still backs up from J20
Single carriageway past Stonehenge creates bottleneck — can add 60–90 min. No viable alternative without major detour
The main road into Cornwall — one of the UK's most reliably awful summer bank holiday bottlenecks
How to Beat Bank Holiday Traffic
1. Travel at Unusual Times
The single most effective strategy is timing. The traffic models are predictable — the busiest periods are Friday afternoon departures and Monday afternoon returns. If you can travel outside these windows, you'll have a dramatically different experience:
- Leave Friday evening after 9pm: Most of the getaway traffic has cleared by then. A 4-hour journey takes 4 hours instead of 7
- Travel Saturday morning before 8am: Day-trippers haven't left yet; roads are clear
- Return Monday morning before 10am: Beat the return wave; enjoy a relaxed journey before the queues build
- Stay an extra night and return Tuesday: By Tuesday morning, bank holiday traffic is essentially zero
2. Use the M6 Toll on Bank Holidays
The M6 Toll is specifically worth its £7.40 fee on bank holiday weekends. While the free M6 through Birmingham (J6–J11) is in standstill, the M6 Toll typically flows freely. The time saving on a bank holiday Friday can exceed 90 minutes for the Birmingham section alone — making £7.40 exceptional value compared to sitting stationary in summer heat.
3. Use Real-Time Traffic Apps
Don't set off without checking live conditions — even the best timing plan can be undermined by an accident or road closure. These apps are essential:
| App | Best for | Standout feature |
|---|---|---|
| Waze | Real-time rerouting | Community-reported incidents, speed cameras, dynamic rerouting around jams |
| Google Maps | Predictive traffic | Shows predicted journey time at different departure times — tap the estimated time to see the graph |
| National Highways | Official road info | Planned roadworks, lane closures, and incident information direct from the road operator |
| Traffic Scotland | Scottish roads | Essential for Highland routes — CCTV cameras, weather conditions, road closures |
| RAC Route Planner | Detailed trip planning | Includes fuel cost estimates, service station locations, and long-range traffic forecasts |
4. Know Your Escape Routes
When the motorway is gridlocked, leaving it is sometimes the right call — but only if you know a credible alternative route. Common escape routes that work:
| Jam | Consider instead |
|---|---|
| M6 Birmingham (J6–J11) | M6 Toll — best option by far. Or A446/A38 for short hop around Sutton Coldfield area |
| M25 (any sector) | A-roads are often slow too — use Waze and let it route dynamically. Avoid pre-planned A-road bypasses as everyone else uses them |
| M5 J19–J23 (Bristol south) | A38 through Bridgwater or coastal B3130 — slower but moving. Somerset Levels roads very narrow |
| A303 (Stonehenge) | A36 via Salisbury or A350 via Warminster — both add distance but can be significantly faster in extreme congestion |
| A30 (Cornwall) | No good alternative — if you're stuck on the A30 into Cornwall on a Friday, there's no real escape. Arrive late night or early morning instead |
5. Prepare Your Car for Delays
If you must travel on a busy day, prepare to spend time in the car:
- Fuel: Fill up before joining the motorway — services will have queues and charge more per litre
- Water and snacks: Even without young children, a 3-hour delay is much less stressful with drinks and food
- Fully charged phone: Navigation and entertainment for passengers; emergency contact
- Pre-downloaded entertainment: Spotify playlists, podcasts, audiobooks, and video content for passengers (ensure screen not visible to driver)
- Tyres and oil: A breakdown in a bank holiday traffic jam causes a major secondary incident — quick checks before you leave
- Allow double journey time: If your journey is normally 3 hours, budget 6 and plan activities at your destination flexible enough to absorb a late arrival
School Holiday Dates 2025
School holidays in England and Wales vary by local authority, but the approximate dates when traffic increases significantly are:

|---|---|---|
| Easter | 7–22 April 2025 | Very High — entire 2 weeks |
| May Half-Term | 26–30 May 2025 | High — coincides with bank holiday |
| Summer | 25 July – 3 September 2025 | Very High — 6-week period |
| October Half-Term | 27–31 October 2025 | High — busy but no bank holiday |
| Christmas | 20 December 2025 – 5 January 2026 | High on 19–23 Dec; quiet 24 Dec–2 Jan |
Frequently Asked Questions
What is the worst bank holiday for traffic in 2025?
August Bank Holiday (22–25 August) is historically the busiest weekend of the year. Easter (17–21 April) is close second. Good Friday afternoon and Easter Monday afternoon are the worst 4-hour windows of either period.
What are the best times to travel on bank holiday weekends?
Before 7am for outbound Friday journeys; before 10am or after 8pm for Monday returns. Saturday morning before 8am is also good. The absolute best option: travel late on Friday night or early Tuesday morning — traffic drops dramatically.
Which motorways are worst on bank holidays?
The M25 orbital (especially near the Dartford Crossing), M6 J6–J11 through Birmingham, M5 south of Bristol (J19–J28), and A303 past Stonehenge. Also the A30 into Cornwall is notoriously congested all summer.
Does the M6 Toll help on bank holidays?
