European Speed Limits 2026 | Safe Stopping Distance Guide
Master speed regulations and stopping distance calculations for your theory test
Speed limits and stopping distances are fundamental topics on every driving theory test in Europe. Understanding them isn't just about passing your test - it's about making split-second decisions that could save lives.
This guide covers speed limits across European countries, the science behind stopping distances, the practical application of following distance rules, and how conditions affect these calculations. These topics frequently appear in theory tests and understanding the principles will help you answer scenario questions confidently.
Understanding Speed Limits by Road Type
Speed limits vary by country and road type. Here are the standard limits across major European countries.
Standard Speed Limits (km/h):
Urban/Built-up Areas:
- Most EU countries: 50 km/h
- Near schools/hospitals: Often 30 km/h
- Residential zones: May be 30 km/h
Rural/Non-urban Roads:
- Single carriageway: 80-100 km/h
- Varies significantly by country
- Watch for posted limits
Motorways/Highways:
- Most EU: 120-130 km/h
- Germany: No general limit (advisory 130 km/h)
- Poland: 140 km/h on some sections
- UK: 70 mph (112 km/h)
Special Limits:
- New drivers: Often lower limits first 1-2 years
- Wet conditions: Some countries reduce limits
- Towing: Lower limits apply
- Heavy goods vehicles: Separate limits
Country Examples:
- Spain: 50/90/120 km/h
- France: 50/80/130 km/h (110 in rain)
- Germany: 50/100/unlimited (motorway)
- Italy: 50/90/130 km/h
- Netherlands: 50/80/100-130 km/h
The Stopping Distance Formula
Stopping distance = Thinking distance + Braking distance. Understanding this formula is essential.
Thinking Distance:
- The distance traveled while you react
- Average reaction time: 0.7 - 1 second
- At 50 km/h = approximately 15 meters
- Increases with speed, fatigue, distraction
- Unaffected by road conditions
Braking Distance:
- The distance to stop once brakes applied
- Increases with the SQUARE of speed
- Double speed = 4x braking distance
- Heavily affected by road conditions
- Affected by vehicle and tire condition
Typical Stopping Distances (dry road):
- 30 km/h: 6m thinking + 6m braking = 12m total
- 50 km/h: 10m thinking + 14m braking = 24m total
- 80 km/h: 16m thinking + 36m braking = 52m total
- 100 km/h: 20m thinking + 56m braking = 76m total
- 130 km/h: 26m thinking + 95m braking = 121m total
Test Tip:
- Memorize key stopping distances for common speeds
- Remember: braking distance quadruples when speed doubles
- Know that thinking distance is roughly linear with speed
The Two-Second Rule
A practical way to maintain safe following distance in normal conditions.
How the Two-Second Rule Works:
- Watch the vehicle ahead pass a fixed point
- Count 'one thousand one, one thousand two'
- You should reach that point after 2 seconds
- If sooner, you're too close
Why Two Seconds:
- At any speed, gives time to react
- Automatically adjusts for speed (faster = more distance)
- Easy to apply while driving
- Works for normal, dry conditions
When to Increase Following Distance:
- Wet roads: Use 4-second rule (double)
- Ice or snow: Use 10+ second rule (or more)
- Fog: Even more distance needed
- Following motorcycles or cyclists
- Heavy vehicles that block your view
- Tired or not feeling alert
Practical Application:
- Use road markings or signs as reference points
- Bridges, lamp posts, road signs work well
- Re-check distance regularly
- If someone cuts in front, ease off to restore gap
- Don't tailgate - it doesn't get you there faster
How Conditions Affect Stopping Distance
Road and weather conditions dramatically change your stopping distance.
Wet Roads:
- Braking distance approximately DOUBLES
- Tire grip significantly reduced
- Risk of aquaplaning at high speeds
- Less margin for error
Ice and Snow:
- Braking distance can be 10x normal
- Even gentle braking can cause skids
- Speed must be dramatically reduced
- Use highest gear possible for traction
Other Factors:
Tire Condition:
- Worn tires = longer stopping distance
- Legal minimum tread depth: 1.6mm (most EU)
- Recommended: 3mm minimum
- Under-inflated tires affect grip
Brake Condition:
- Worn brakes = longer stopping
- Wet brakes (after water) reduced effectiveness
- Test brakes after driving through water
Vehicle Load:
- Heavier vehicle = longer stopping distance
- Load affects balance and braking
- Adjust following distance accordingly
Road Surface:
- Gravel, mud, leaves reduce grip
- New asphalt can be slippery
- Metal surfaces (bridges, tram tracks) slippery when wet
- Road markings can be slippery
Overtaking Distance and Safety
Safe overtaking requires understanding of speeds and distances involved.
Calculating Overtaking Distance:
- Distance to reach and pass the other vehicle
- Distance the oncoming vehicle travels during overtaking
- Safety margin on both ends
- At highway speeds, can require 400+ meters clear road
Safe Overtaking Checklist:
- 1Is it legal? Check signs, markings
- 2Is it necessary? Will it really help?
- 3Is there enough clear road ahead?
- 4Can you see far enough?
- 5Is anyone behind also overtaking?
- 6Check mirrors, blind spot
- 7Signal, accelerate, pass decisively
- 8Return to lane only when clear
When NOT to Overtake:
- Solid center lines
- Near junctions, bends, hills
- Can't see far enough ahead
- Near pedestrian crossings
- Road narrows ahead
- Uncertain of clear distance
- Speed would exceed limit
Common Overtaking Errors:
- Underestimating distance needed
- Not accounting for oncoming speed
- Hesitating mid-overtake
- Cutting in too early
- Not checking mirrors first
Speed Management in Different Zones
Adapting your speed to different environments is a key skill tested in theory exams.
Urban/City Driving:
- Default 50 km/h unless signed
- Watch for lower limits near schools
- Expect pedestrians, cyclists, buses
- Be ready to stop at any moment
- 30 km/h zones increasingly common
Rural Roads:
- Limits vary widely (80-100 km/h typical)
- Hidden hazards: tractors, animals, debris
- Limited escape routes
- Often no street lighting
- Adjust for narrow roads, sharp bends
Motorways/Highways:
- Higher limits but greater consequences
- Maintain consistent speed
- Use right lane except when overtaking
- Watch for speed limit changes (roadworks, weather)
- Variable speed limits increasingly common
Special Zones:
- School zones: 30 km/h during school hours
- Hospital zones: Often reduced limits
- Residential areas: 30 km/h common
- Parking areas: Walking pace (5-10 km/h)
- Roadworks: Follow signed temporary limits
Remember:
- Speed limits are MAXIMUM not TARGET speeds
- Conditions may require driving well below the limit
- Common sense overrides posted limits
Frequently Asked Questions
Q1What happens if there is no speed limit sign?
Default (national) speed limits apply when no specific limit is signed. These vary by country and road type. Generally: 50 km/h in built-up areas, 80-100 km/h on rural roads, and 120-130 km/h on motorways. Always know the default limits for your country.
Q2How much does rain affect stopping distance?
Rain approximately doubles your braking distance. On a wet road at 80 km/h, your stopping distance increases from about 52 meters to around 96 meters. This is why you should double your following distance in wet conditions (4-second rule instead of 2-second rule).
Q3Are there lower speed limits for new drivers?
Yes, many European countries impose lower speed limits for new drivers during a probationary period (usually 1-2 years). For example, France limits new drivers to 110 km/h on motorways instead of 130 km/h. Check the rules specific to your country.
Q4Is there a tolerance on speed limits?
While some speed cameras have a small tolerance (typically 2-3 km/h or 10%), you should never rely on this. Speed limits are legal maximums, and exceeding them can result in fines regardless of small margins. Always aim to stay within the limit.
