This paper examines the case for raising the Swedish speed limit for heavy vehicles from 70 km/h to 80 km/h. The VTI traffic simulation model has been used to analyse the expected changes in speed for heavy vehicles and overtakings between passenger cars and heavy vehicles. Calculations have also been done concerning changes in the number of meetings between cars and lorries which would result from a chnage in the lorry speed limit. The simulation results and accident models, which describe the relationship between speed and accidents rate and severity, have been used to estimate the changes in accident rates for different types of accidents on two-lane roads with the speed limit of 90 km/h for other vehicles. The total analysis also includes, beside the increased speed limit for heavy vehicles, the additional use of speed limiter on heavy vehicles, which regulate the maximum speed to 85 or 93 km/h.
