Since October 1, 2026, every cyclist on a Spanish interurban road, meaning one outside a built-up area, must wear a helmet, and the old exemptions are gone. Inside towns the duty is narrower: it covers riders under 16 and people who ride a bicycle for work. An adult cycling for fun on a city street is not named in the helmet article, although the DGT (Dirección General de Tráfico), Spain’s traffic authority, advises a helmet on every road.
Who must wear a helmet, and where
The rule sits in article 118.2 of Spain’s General Traffic Regulation (Reglamento General de Circulación), as rewritten by Royal Decree 518/2026. It addresses the rider and, where there are any, the passengers on bicycles and cycles.
| Who is riding | Helmet required? | Notes |
|---|---|---|
| Any cyclist on an interurban road (outside built-up areas) | Yes | The exemptions that used to apply were removed on October 1, 2026. |
| Rider or passenger under 16, on any road | Yes | This includes city streets. |
| Professional rider (a delivery rider, for example) | Yes | Outside built-up areas the general rule covers them; the text adds urban roads and travesías. A high-visibility vest is required too. |
| Adult cycling for leisure or commuting on a city street | Not under article 118.2 | The DGT recommends a helmet on all roads. |
What changed on October 1, 2026
The decree is dated June 24, 2026 and took effect on October 1.
Two changes matter for the helmet rule. The exemptions that had applied were removed, and the decree’s preamble calls them pointless. The same preamble also establishes a helmet duty for people who ride a bicycle as their work. The DGT summary puts “helmet mandatory for all cyclists” under its interurban heading, which is the broadest part of the rule, not the whole of it.
The reform reaches beyond helmets. Outside built-up areas, a driver passing a cyclist must reduce speed by at least 20 km/h (about 12 mph) relative to the road’s limit. The DGT’s list adds riding preferably in the middle of the lane on urban roads, and the decree changes how passengers may be carried on bicycles (see children, below).
Interurban road, travesía or city street: which are you on?
Annex I of the Traffic Act defines an interurban road (vía interurbana) as a public road outside a built-up area (poblado) and an urban road (vía urbana) as a public road inside one, except travesías. A travesía is a stretch of highway that runs through a built-up area, so by definition it is neither urban nor interurban. The town-entry and town-exit signs mark where a built-up area starts and ends.
Article 118.2 follows those categories. Its general helmet duty is worded for interurban roads, so for an adult it applies outside built-up areas. Travesías appear only in the sentence about people who ride for work, and riders under 16 are covered on every road. The DGT advises a helmet on all roads whatever the legal minimum. Because a ride can cross all three kinds of road unnoticed, wearing the helmet throughout is simplest. The text speaks of riders of bicycles in general, so visitors should plan on the same footing; see our guide to planning a cycling holiday.
Which helmet counts, and when to retire it
For bicycles, the article asks for a helmet that is “homologado o certificado” (approved or certified) under current legislation, worn properly fastened. It names no technical standard, unlike the UNECE R22 it requires for mopeds and motorcycles. The Bicycle Helmet Safety Institute (BHSI) notes that Europe has a CEN standard covering all member states; ask the seller which standard your helmet is certified to, and keep the strap done up. Fit and construction are covered in our helmet guide.
A legal helmet protects only while it is intact. Stop using it and replace it if any of these is true:
- You crashed and your head hit anything. BHSI explains that the foam is built for one use and protects less once crushed, even if it looks fine.
- The shell shows marks or the foam shows any crush.
- You dropped it hard enough to crack the foam.
- You cannot adjust it to fit correctly.
If you are unsure whether a crash damaged it, BHSI says most manufacturers will inspect a crashed helmet.
Riding at night: the 150-meter rule
The same article adds a night-time rule. Between sunset and sunrise, or whenever weather or ambient conditions sharply cut visibility, a cyclist must use at least one luminous or reflective element visible from at least 150 m (about 490 ft). The article ties the 150 m figure to interurban roads and requires the element to conform to the rules on personal protective equipment (“conforme a la normativa de los equipos de protección individual”).
That element is not the whole of night-time equipment. The DGT’s bicycle guide, last updated in November 2022, calls for a white position light at the front and, at the rear, a red position light plus a non-triangular red reflector; it predates the reform, so check the DGT page for updates. Treat the 150 m element as the minimum this article sets, not a lighting plan; our cycling lights buyer’s guide helps you choose lights.
Children and family rides
Because article 118.2 names passengers as well as riders, a child under 16 in a bike seat falls under the same helmet duty as a child pedaling their own bike, on any type of road.
Carrying the child is governed by a new article 154, in force since October 1, 2026. It allows cargo and passengers on bicycles if the rider is an adult and the technical requirements are met. A bicycle built for one person may carry a child of up to 22 kg (about 49 lb) who can sit up alone, only in an additional seat that meets specifications to be set by an Interior Ministry order. Until that order enters into force, the decree says additional seats must be approved (homologados). On interurban roads, article 154 ties these rules to daylight and conditions that do not reduce visibility.
The DGT’s bicycle guide, last updated in November 2022, still states a different rule: one passenger, under 7, in an approved additional seat. It predates the reform, so follow the 2026 text. For seats, trailers and cargo bikes, see cycling with kids.
E-bikes and mopeds
Article 118.2 speaks of bicycles and cycles; mopeds fall under article 118.1, which asks for a helmet approved to UNECE R22 on every type of road. Which category an electric bike falls into depends on how it is classified, so confirm that for your model first. The wider picture for the US, UK and EU is in our e-bike laws overview.
Check before you rely on this
This page covers Spain’s national rules as of October 2026. Town councils have their own traffic ordinances, and the decree’s preamble says council requests to adapt them were one reason for the cycling changes, so check local rules where you ride. The definitions above come from the BOE’s consolidated Traffic Act, which the BOE labels informational and without legal value; for legal purposes consult the originally published text. If you think you are an exception, ask the DGT rather than assume.
