The Public Health Agency's new advice means that mouth guards must be worn in public transport during rush hour on non-holiday weekdays - between 07 and 09 in the morning and between 16 and 18 in the afternoon.

It is primarily the travelers' own responsibility to bring protection, but at the same time the Swedish Public Health Agency has recommended that companies that operate public transport provide oral protection to those travelers who have not had the opportunity to bring their own.

In SL's traffic, it is only at the customer centers at Sergels torg and Centralen that you can get free mouth protection.

"The availability may vary, however, and it is not guaranteed that mouth protection is always available," SL writes in a press release.

In the clip above, SL's communications manager Suss Forssman Thullberg tells how SL intends to provide mouth protection for those travelers who have nothing.

Travelers without mouth guards will not be rejected

According to Swedish Public Transport, the organization for the country's public transport company, passengers who do not have mouth guards will still be allowed to board the vehicles and will not be rejected during their journey.

"It is neither the driver's nor any other personnel's responsibility to monitor compliance with the recommendation," writes Swedish Public Transport in a press release in which the individual's own responsibility is emphasized.
