Abstract
When slopes are very steep (1:1) vehicles will overturn in slope incidents. Slopes can be relatively steep (gradients 1:2 to 1:3) if they have an obstacle free zone (See for Part I: PB 26461). Part II discusses in detail the determination of the influence of the different characteristics of slopes on the results of slope- incidents and specifically how such slopes should be designed if their are obstacles like trees or ditches. Mathematical simulations are made with the VEDYAC computer program.
