- 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 tyres for the two vehicles, restoring the values to the correct ones if they are found to be incorrect.

- Also check the condition of the wheel rims, making sure they are not distorted or broken, and replacing them if any faults are found.

- Carry out the test on a route where there are left and right hand bends of varying degrees, evaluating the dipping 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 occur, leading to unsafe driving during this manoeuvre.

- Then carry out a road test on an uneven road (transverse rails, cobblestones, paving stones) with right/left hand bends of varying 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 performance of the vehicle in terms of rolling/pitching in accordance with the attached table.

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