Multiple official sources, including National Highways, Traffic England, the RAC, and the AA, show no active M3 incidents as of the latest checks on 28 November 2025.

The M3 motorway, stretching 59 miles from Sunbury-on-Thames to Southampton, is one of the UK’s busiest commuter routes. It is frequently monitored for incidents, with 68 traffic cameras operated by National Highways providing real-time updates every few minutes. Despite this comprehensive coverage, no accident or emergency situation has been reported on the M3 today.

The only significant motorway event currently highlighted by National Highways involves a broken-down vehicle on the M25 anticlockwise between junctions 17 and 16. For drivers seeking information about the M3, official monitoring tools and live camera feeds remain the most reliable sources for real-time updates.

What happened in the M3 accident today?

No M3 accident has been reported today. Comprehensive checks across all official traffic monitoring channels, including National Highways travel alerts and Traffic England, show no collision, crash, or incident on any section of the M3 motorway.

General motorway alerts from National Highways are updated every five minutes to cover unscheduled priority incidents across England. The latest checks specifically exclude any M3 activity, confirming the motorway is operating normally with no reported accidents.

Where is the M3 accident located and is it causing delays?

Since no accident exists on the M3 today, there is no incident location or associated delay to report. The motorway remains fully operational in both directions.

The M3 is nonetheless known for several congestion hotspots where accidents occur more frequently. Understanding these areas helps drivers remain vigilant:

• Junctions 2–3: Tricky interchanges near the M25 junction 12 and Lightwater create complex lane splits that frequently cause traffic build-ups.
• Junction 9: Links directly to the A34 near Winchester; fast-moving traffic on this section results in regular incidents.
• Junction 10 (Chilcomb): Experiences significant congestion from Southampton-bound traffic using the A31.
• Junction 12: Double roundabouts frequently generate queues on the A335 toward Allbrook.
• Between J11–J12: High traffic volumes from Winchester and Otterbourne areas contribute to regular congestion.

What are the live updates on the M3 incident?

There is no M3 incident to report live updates for. All official monitoring channels, including RAC Route Planner traffic news and the AA Route Planner, confirm normal traffic conditions on the M3.

For those seeking real-time information, several official tools provide continuous updates:

• Traffic England: Traffic England provides up-to-date alerts and traffic conditions across the motorway network.
• National Highways travel alerts: Updated every five minutes with priority incident information.
• Live traffic cameras: Traffic Cameras UK offers real-time visual feeds from M3 cameras.
• Motorway cameras: Motorway Cameras provides comprehensive coverage updated regularly.

These tools remain the most reliable sources for checking current M3 conditions before or during any journey.

Is the M3 closed due to the accident?

The M3 is not closed. No road closures, diversions, or traffic management measures are in place on the M3 motorway today. The motorway operates normally with full lane access available in both directions.

Peak-hour congestion may still affect travel times on this busy route, particularly around known hotspots between junctions 2 and 12. These delays, where they occur, result from normal traffic volumes rather than any incident or accident.

M3 Motorway Context and Accident Risk Areas

The M3 serves as a critical link between London and Southampton, carrying significant daily traffic volumes. Its design, particularly around several junctions, creates conditions where incidents are more likely to occur.

The stretch between Sunbury-on-Thames and Southampton passes through varied terrain and interfaces with multiple other major routes, including the M25, A34, and A31. These intersections create merge points where higher accident rates have been observed historically.

Peak travel times, particularly weekday mornings and evenings, see the highest traffic volumes on the M3. The southbound carriageway often experiences congestion near Winchester during afternoon hours. Weather has not been cited as a contributing factor to any current conditions, though drivers should remain aware that adverse weather can increase risk across all motorway sections.
