blog 3 vehicle safety systems

For this task we had to check the safety systems of three different cars, and one of which I will blog about, safety systems can range from the airbags to seatbelts and a lot of the items that are in the interior of the car along with some external parts like windscreen wipers.

The first part of the task was to list 9 different safety components found in the vehicle, the vehicle I was testing was a 1998 Mazda Familia, but since the vehicle was quite basic I could only list 6.

1.)Driver side srs Airbag
2.)Handbrake
3.)Front and rear Seatbelts
4.)Park Lights
5.)Anti-lock Brake system
6.)Child lock (rear doors)

Next the check list for the safety system began, but first we had to list number of seatbelts and what type they where and the car class.

Vehicle Class-MA
Type of Seat belts(front)-L/D (Lap Diagonal) Number of belts-2
Type of seat belts(rear)-L/D Number of Belts-2 (and 1 Lap belt)

Vision
-Windscreen: PASS
-Sun Visors: PASS
-Wipers: FAIL

-rear view mirrors: PASS

Reason for wipers failing the test was there was no rubber on the right hand side windscreen wiper meaning driver vision can be impaired causing an accident.

     -Right Rear: PASS
-Spare wheel security: (No spare wheel)PASS
-Wheels: PASS
-Hubs and axles: PASS

The reason the left front tyre failed was because the rim was badly buckled and one of the wheel studs/nut/bolt was missing which would make the wheel unstable and it could potentially fall off due to not being well secured.

Towing Connections
-Towing connection: PASS



These are all the tests that can be done to check the safety system of a car and the reasons why the mazda familia failed on some parts of the test.
