The article presents an analysis of the current risk of accidents resulting from road freight transport. This includes calculations that led to the numerical characteristics of the risk caused by the movement of trucks. The characteristics of the threat are presented, taking into account the circumstances of time (day, week, month). The significance of this risk increases with the persistence of a strong and sustained upward trend in road freight transport in Poland. The growth rate of truck traffic for the last 10 years is almost two times higher than passenger car traffic. Estimation of risk indicators and risk of fatalities was based on an analysis of the collection of accident extracted for this purpose. The event analysis period covers the years 2010-2011 and the numerical values were referred to classical measurements of drivers' working lives. The calculations made it possible to show not only the participation of this category of vehicles in the creation of a substantial part of the accident risk. First of all, they showed a changing nature of this participation and indicated periods of time when there is a concentration of the accident risk and the highest indicator of the mortality risk in accidents involving trucks.
