Functional / Operational Based on averages and considerations from different countries -bothregulatory and from manuals from Latin Americaa slope of between 12-10% can,for example, be used only for very small heights, such as a step of up to 20 centimeters. Drive slowly and carefully when going up or down the ramp. The slope can be expressed as a percentage thatresultsfrom theratio between the height to beovercome (h) and thelengthof the horizontal plane (d), multiplied by 100. (A) On roadways where there are more than two lanes inclined in the same direction, the cross slope may be increased by 0.5% to 1% for each additional lane, up to a maximum of 3%. Even the slightest of angles can lead to tip-overs. Again, as the heights require greater efforts, the slopes are reduced to reach, for example, 8% for heights that go up to 75 centimeters; 6% for up to 150 centimeters; and 5% for the elderly.
