1. A system for use in classifying a vehicle, said system comprising:
- a capacitive sensor for operatively receiving a weight of a vehicle; and
a capacitance detector coupled to said capacitive sensor, said capacitance detector adapted to determine a capacitance signal of said capacitive sensor in response to said capacitive sensor receiving the weight; and
wherein said capacitance detector is adapted to determine a width of at least one tire of the vehicle passing over said capacitive sensor based on the capacitance signal.
