Road planning

This LAP indicates if hydrogen has to follow specific requirements when transported, and if the regulations are different from the transport of other types of gas. It identifes the competent authorities to allocate the routes.


Road Planning provide the municipalities with a clear understanding of the maximum risks that the transport of hazardous substances may cause. Baseline goals are: Transport hazardous substances between major industrial sites and abroad, including in the future, keeping risks for locals along the routes within legal limits, provide clarity to municipalities about what may / may not be built.

Pan-European Assessment:

Hydrogen is considered as any other flammable gas or dangerous good for its transportation. The Agreement of transport of Dangerous Goods by Road applies.
Is it a barrier?
Assessment Severity
Identification the requirements for transport of hydrogen by road.


Question 1 Are there any specific regulations or restrictions on the road transport of hydrogen? A) Does hydrogen have to follow specific requirements when transported? (e.g. specific types of roads, specific route)
Requirements for gases Class II, code F ADR apply for transportation of hydrogen.
Question 1 Are there any specific regulations or restrictions on the road transport of hydrogen? B) Please specify the requirements regarding tunnels, bridges, parking, others
The requirements in tunnels, bridges, parking or other, heavy vehicles transporting dangerous substances (vehicles with a gross mass exceeding 3.5 tonnes) must be identified according to the Dangerous Goods Transport Regulations by road, RPE with an orange panel . Examples of these situations are: Bridge in Lisbon, called 25th of April Bridge: Traffic on the Bridge and the North Viaduct of vehicles transporting hazardous substances is only allowed between 2 and 5 pm every day of the week, Sundays and public holidays. Tunnels: Period / Time of restrictions (without exception): all year Forbidden routes: Gardunha Tunnels A23 Important: with the exception of the existing restrictions for the Gardunha tunnel, approved by Ordinance, the restrictions on heavy vehicles in Ramela Barracão Tunnels come from vertical signalling under the concession agreement between the State and SCUTVIAS. Exceptions (applicable to all prohibited routes except 25th of April Bridge, Gardunha, Barracão and Ramela Tunnels): Vehicles transporting dangerous substances to the armed, militarized and police forces Vehicles carrying dangerous goods from ships or intended for loading Vehicles carrying fuels for the supply of airports and seaports
Question 2 Which authorities are competent to allocate the routes? (and at what level: national, local?)
National level – Ministry of Infrastructure and Construction
Question 3 Are the regulations differing from the transport of other types of gas?
There are no significantly different or higher requirements for the transport of hydrogen in relation to petrol or diesel. The truck or driver does not require any additional permissions for hydrogen transport.
