Skiing abroad: what changes at the border, and the kit that travels.

Helmet laws change with the country

• Italy: helmets compulsory for under-18s in alpine skiing, snowboarding and telemark from 1 January 2022 (d.lgs. 40/2021), and reported extended to everyone, sledging included, from the 2025-26 season. ADAC (21 October 2026) adds that CE-certified helmets are required. Both rules rest on secondary legal news and press; the official texts were not read.
• Austria: no national law; seven of nine provinces require helmets for children under 15, and Tyrol and Vorarlberg do not (ADAC).
• Switzerland, Germany and France: no legal requirement, children included (ADAC). In France, ADAC says the sports ministry strongly recommends helmets and ski-area operators may set local rules.
• Nova Scotia: all ages since 1 November 2012, with helmets to ASTM, Snell, CSA or CEN standards. New Jersey: under-18s since the 2011-12 season.

Penalty amounts are left out. The full table is on youth helmet rules, and the standards a helmet label may show are in the helmet guide.

Two codes of conduct

Two codes are set out here, one from FIS and one from the NSAA. The FIS Code of Conduct for Skiers and Snowboarders has ten rules (its current file dates from 24 August 2023, with the same substance as the 2016 version), and FIS's 2016 comments say failing to respect them could expose a person to civil and criminal liability after an accident. The Swiss BFU says people on Swiss pistes must follow the FIS rules and those of SKUS, the Swiss commission for snow-sport runs. The NSAA's Your Responsibility Code grew from seven points to ten in 2022, and NSAA notes older seven-point signs may still be seen. The two overlap on control, right of way, stopping, looking uphill and signs; only the NSAA code has explicit points on runaway equipment, closed terrain, lifts and impairment, and only the FIS code covers overtaking, walking on the piste and the duty to assist. Cross-country has its own FIS code (6 September 2023). After an accident, FIS Rule 10 requires names and addresses to be exchanged, and NSAA point 10 adds a ski-area employee. The full texts are on the codes of conduct.

Trail colours do not mean the same thing everywhere

There is no single world system, and ratings are relative within one ski area.

• United States: Colorado law (C.R.S. 33-44-107) requires a green circle ("easiest"), blue square ("more difficult") and black diamond ("most difficult"), two black diamonds with "EX" for extreme terrain and an orange oval for freestyle terrain. Arizona's law (A.R.S. 5-703) words the green circle "easier".
• France: the AFNOR standard NF S 52-102 sets run marking. The Ministry of Sports said in 2012 that these standards are voluntary but often written into mayors' orders, which makes them compulsory locally. One such order (L'Argentiere-La Bessee, December 2022) classes runs green, blue, red and black, and says any unmarked route is not a ski run but off-piste.
• Austria: Austrian Standards lists ONORM S 4611 (2016-08-01) as the basis for classifying and signing runs; Wikipedia names the standard ONORM S 4610. The colours were not seen in the listing.

Avalanche scales, altitude and lifts

Both the North American and European avalanche danger scales have five levels, but the top one is "Extreme" in North America (Avalanche.org) and "Very high" in Europe (EAWS). Leaving marked runs is covered in the backcountry and avalanche kit guide, which starts with avalanche training. NHS 111 Wales says altitude sickness usually occurs above 2,500 metres and can sometimes be life-threatening; it needs medical care (see cold and altitude). Lifts are regulated by different bodies: in Switzerland the Federal Office of Transport supervises federally licensed cableways and the cantons the smaller ones; in British Columbia, Technical Safety BC; in Colorado, a state tramway board, according to a search summary of a rulemaking notice. See lift safety regulators.

Kit that travels, and kit that is hired

Bindings are set by a binding technician, at home or abroad; this site gives no release values. The BFU recommends a specialist check on a test device before the season. A standard for sampling and inspecting ski-binding-boot systems in rental shops, ISO 13993, was at draft international standard stage when the research searched. Travellers who bring their own boots and hire skis meet the sole-and-binding question: alpine boots fall under ISO 5355, or under ISO 23223 where they have walking soles, and the makers' compatibility lists say which bindings take which sole (see boots and sole norms). Airline baggage rules were not researched and are not given here.
