Spain just updated its traffic regulations — and if you ride on Spanish roads, some of these changes affect you directly. The new Royal Decreto 518/2026 was published in the BOE on 26 June 2026 and amends the General Traffic Regulations (Reglamento General de Circulación). The DGT describes it as a shift away from vehicle-first thinking toward people-first mobility. For cyclists that sounds good on paper — here’s what it actually means on the road.

Helmets Outside Towns: Now Mandatory, No Exceptions

This one is clear cut. On any road outside a built-up area, a helmet is now compulsory. There are no longer any exemptions — not for heat, not for gradient climbs, not for any other reason.

If you ride professionally, there’s an additional rule: a reflective vest is required when working. That covers guides, couriers, race support riders, and anyone else using a bike as part of their job.

For most of us riding the Costa Blanca’s interurban roads and mountain routes, the practical message is simple: helmet on before you leave town.

Overtaking: The Rules for Drivers Just Got Tighter

This is probably the most significant change for safety. When a motor vehicle overtakes a cyclist on an interurban road, the driver must now:

• Reduce speed by at least 20 km/h below the road limit — not just slow down a bit, but a measurable reduction
• Keep at least 1.5 metres of lateral clearance — the minimum distance rule that many countries have had for years is now law in Spain
• Change lane completely when there is more than one lane in the same direction

That last point matters. On a two-lane road heading out of Altea or up toward Jalón, a driver can no longer just nudge wide — they have to move into the other lane properly.

The law also now treats a group of cyclists as a single moving unit for overtaking purposes. So a driver behind a group of ten riders has to treat the whole group as one vehicle, not attempt to thread through gaps.

Urban Cycling: More Space, More Rights

In towns and cities, the new rules put bikes more clearly in the flow of traffic rather than at the edge of it:

• Cyclists should generally ride on the carriageway, preferably in the centre of the lane
• Motor vehicles must keep a minimum of 5 metres from a cyclist when following in the same lane
• Cyclists may overtake motor vehicles on either side in congested urban traffic — so filtering past stationary cars is now explicitly permitted
• On one-way 30 km/h streets, local authorities can designate two-way cycling where properly signposted

If you do any riding through Alicante, Benidorm, or Torrevieja, the centre-of-lane guidance is worth knowing. Riding in the middle of a slow lane is often safer than hugging the kerb, and the law now backs that up.

Shoulder Use and Riding Two Abreast

The rules on the arcén (hard shoulder) haven’t changed dramatically. Bicycles may still use the shoulder where it’s passable and wide enough. Riding two abreast on the shoulder, or on the usable part of the carriageway where permitted, remains allowed.

For anyone used to riding the CV roads on the Costa Blanca, most of this will feel familiar. The shoulder rules were already fairly clear — this reform doesn’t tighten them.

“Vulnerable Road Users” Now Has a Legal Definition

One change that’s easy to overlook but actually matters: Spanish traffic law now formally defines vulnerable road users for the first time. Cyclists, pedestrians, motorcycle riders, and VMP users (e-scooters and the like) are included. This matters because it’s the foundation that future protections build on — once you’re defined in law, enforcement and penalties can be calibrated around that.

The reform also introduces a new Title VI covering urban circulation rules and strengthens requirements around special lanes and vehicle behaviour near stopped vehicles.

When Do the Changes Take Effect?

The decree was published on 26 June 2026. Several sources indicate the cycling-specific rules come into force from October 2026, though you should check the official BOE text for the precise implementation dates.

The Bottom Line

Interurban riding gets meaningfully better protection under this law — the overtaking rules in particular are a genuine improvement. Urban cyclists get clearer rights to road space. And the helmet rule outside towns, while not new in spirit, now has no grey areas.

If you drive on Costa Blanca roads as well as ride them, make sure you’re up to speed on the overtaking changes. The 20 km/h reduction and full lane change requirements catch a lot of drivers off guard.
