Latest figures show fatalities have risen to 320 between the beginning of the year and the end of August, from the 293 deaths registered during the same period of last year.
However, the number of people who lost their lives on Portuguese roads so far this year, is slightly down when compared with 2013, when 327 deaths were counted over the first two-thirds of the year.
The biggest increases were recorded in Aveiro, Beja and also in the Algarve, where the number of people who died in collisions has soared by almost 80 percent when compared with 2014.
The districts with the highest number of deaths were Lisbon and Oporto, each recording 34 fatalities, up one and three respectively on last year’s figures. Nationwide, the total number of serious injuries, of which some usually result in deaths at a later stage, also increased in 2015, totalling 1,434 as opposed to 1,398 last year.
