The DGT has changed the rules for overtaking cyclists, and from October 1, 2026, drivers in Spain must follow stricter requirements or face penalties. The reform, approved in June and confirmed through Royal Decree 518/2026, modifies the General Traffic Regulations and introduces a mandatory speed reduction before any overtaking maneuver.
This is not just a minor tweak. The new rules aim to protect vulnerable road users by addressing both the lateral distance and the aerodynamic effects that occur at higher speeds. Here is everything you need to know to avoid surprises and stay compliant.
What Exactly Changes on October 1?
Until now, drivers were required to maintain a minimum lateral separation of 1.5 meters when passing a cyclist. That requirement remains, but the new regulation adds a crucial speed component. Before initiating the overtaking maneuver, drivers must reduce their speed significantly.
The change applies to all roads, but the specific speed rule varies depending on the type of road. The goal is to minimize the risk of collisions and reduce the severity of any incident involving cyclists.
The New Speed Rule for Interurban Roads
On interurban roads, drivers must reduce their speed by at least 20 km/h below the posted speed limit for that section, both before and during the overtaking maneuver. In practical terms, on a conventional road with a 90 km/h limit, no overtaking maneuver can be completed at more than 70 km/h.
This means you cannot simply maintain your current speed and swerve around a cyclist. You must actively slow down before you even begin to pass. The rule is designed to give you more time to react and to reduce the aerodynamic impact on the cyclist.
Why the Speed Reduction Matters
The new rule is not arbitrary. At higher speeds, the aerodynamic turbulence around a cyclist becomes more severe. A passing vehicle first pushes the cyclist outward as it approaches, then pulls them inward as it passes. This phenomenon, linked to the Venturi effect, can destabilize even experienced riders.
By forcing drivers to slow down, the regulation reduces the strength of these air currents and gives cyclists a better chance to maintain control. It also increases the driver's reaction time, which is critical in emergency situations.
Key Takeaways for Drivers
- 1.5-meter lateral gap remains mandatory when overtaking cyclists.
- Reduce speed by at least 20 km/h below the limit on interurban roads before and during overtaking.
- Applies from October 1, 2026 under Royal Decree 518/2026.
- Penalties apply for non-compliance, including fines and possible points loss.
- Aerodynamic safety is a key reason for the change, addressing the Venturi effect.
Comparison of Old vs. New Overtaking Rules
| Aspect | Old Rule (Before Oct 1, 2026) | New Rule (From Oct 1, 2026) |
|---|---|---|
| Lateral separation | 1.5 meters | 1.5 meters (unchanged) |
| Speed reduction on interurban roads | Not specified | At least 20 km/h below limit |
| Timing of speed reduction | Not required | Before and during maneuver |
| Penalties for non-compliance | Yes, for gap violation | Yes, for gap and speed violation |
Who Is Affected and What Are the Penalties?
All drivers who overtake cyclists on Spanish roads are affected. This includes both professional and private drivers. The penalties for non-compliance are expected to be enforced through fines and possibly points on your license, although the exact amounts have not been detailed in the available information.

Ignoring the new rules can be costly. The DGT has emphasized that the reform is about saving lives, not just adding bureaucracy. Cyclists are among the most vulnerable road users, and the new speed requirement is a direct response to the aerodynamic risks they face.

What to Watch Next
As October 1 approaches, drivers should familiarize themselves with the new speed limits and practice reducing speed before overtaking. The DGT may launch awareness campaigns, and enforcement will likely increase in the first months. A closer look at the same subject appears in A fine of up to 8,000 euros!

FAQ
When do the new DGT rules for overtaking cyclists take effect?
The new rules take effect on October 1, 2026, following approval in June and confirmation through Royal Decree 518/2026.
What is the new speed requirement on interurban roads?
Drivers must reduce their speed by at least 20 km/h below the posted limit before and during the overtaking maneuver. For example, on a 90 km/h road, you cannot exceed 70 km/h while passing a cyclist.
Why is the speed reduction necessary?
The reduction minimizes the aerodynamic turbulence (Venturi effect) that can destabilize cyclists at higher speeds and gives drivers more reaction time.
Does the 1.5-meter lateral gap still apply?
Yes, the 1.5-meter minimum lateral separation remains mandatory. The new rule adds a speed component on top of the existing gap requirement.
