Project cost ($):
1 hour to prepare, 1 day for experiment
4 cars, 3 of which are of a similar make and model are required. Fog machines will need to be leased for the purposes of this experiment
Be careful to avoid any accidents. Always have someone on standby to alert the drivers, to prevent them from colliding into the stationery cars

This experiment was done to investigate the effectiveness of using 1 rear fog light on the rear of a vehicle to assist in the estimation of distance, compared with 2 rear fog lights and and no fog lights at all.
The use of 2 rear fog lights will improve the driver's ability to estimate distance.
The materials required for the experiment:
1. For this experiment, the independent variable is the number of fog lights on the car. The dependent variable is the distance between the cars. The distance is measured using a measuring tape. The constants (control variables) are the amount of fog created by the 2 fog machines, the make and model of the cars used for the experiment and the driving experience of the participants.
The results show that using 1 rear fog light and no rear fog lights causes the stationary vehicle to appear further away than it actually is.
The hypothesis that the use of 2 fog lights will improve the estimation of distance by drivers is proven to be true.
The experiment can also be done by adjusting the height of the fog lights.
