ROAD TEST FOR ROLLING/PITCHING EVALUATION

Check 44B

Carry out a road test on traffic free roads in safe conditions following the highway code.

Before proceeding with the test, check the inflation pressure of the two vehicles, restoring the values to the correct ones if they are found to be incorrect.

Before proceeding with the test, check the tyre inflation pressure of the two vehicles, restoring it to the correct values if it is found to be incorrect. Also check the wheel rim conditions, checking for distortions or breaks, replacing them if they are found to be faulty.

Carry out the test on a route where there are left and right hand bends of different degrees, evaluating the laying down speed of the vehicle round the bends, trying to take the bends at a constant speed, avoiding carrying out pull/release manoeuvres.

Evaluate the stability of the vehicle by simulating a lane change/overtaking and check that violent vehicle reactions do not appear leading to unsafe driving during this manoeuvre.

Then carry out a road test on an unmade road (cobblestones) where there are right/left hand bends of different degrees to evaluate the tendency of the rear of the vehicle to lose grip.

This type of test should always be used for comparison with a new vehicle or reference vehicle of the same trim level and engine type, available in the workshop at the time of the test in question.

At the end of the test in question, assess/rate the behaviour of the vehicle in terms of rolling/pitching in accordance with the enclosed table.

The reference vehicle has a rolling/pitching default rating of 7.
