H4 — Tolls and vehicle classes on this road

Vehicles with a maximum authorised mass of up to 3.5 t need an e-vignette on signposted DARS toll motorways and expressways. Check the vehicle class and validity linked to the registration plate before departure.

Vehicles above 3.5 t use the DarsGo distance-based toll system on toll sections. Charges also depend on vehicle type, axle count and emissions class.

H4 crosses the Vipava Valley towards Vrtojba. Official strong-wind vehicle restrictions must be checked separately from toll information.

These are permanent toll rules, not statements about current closures or vehicle restrictions.

H4 — Road sections: what matters on the route?

H4 connects A1 at Razdrto with the Vipava Valley and Italy at Vrtojba. The Rebrnice section is exposed to Bora winds, but the forecast itself is not an official driving ban.

Major road connections and checkpoints

Razdrto / Nanos / Rebrnice

The Razdrto/Nanos–Rebrnice section is exposed to strong winds. PIC documents a separate Bora restriction system for H4; it does not imply the road is currently closed.

Vipava / Ajdovščina

H4 continues through Vipava and Ajdovščina. Weather can vary between sections; vehicle restrictions depend on official measurements and operator decisions.

Selo / Šempeter / Vrtojba

The western continuation from Selo and Šempeter reaches Vrtojba at the Italian border. For onward travel, check Italian traffic information too.

Practical questions and answers

Does forecast Bora wind mean H4 is closed?

No. A weather forecast does not decide road access. Authorities issue vehicle-specific restrictions and closures from actual conditions; check Promet.si.

Are Bora rules on R2-444 identical to H4?

Do not assume so. PIC describes the regional-road monitoring zones and H4 restrictions separately; check the exact road and direction.

This is permanent geographic and regulatory context. Check current closures, vehicle restrictions, weather and border conditions separately using up-to-date official data.
