- 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.

- 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 rod (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".
