Q1. What does the barrier-less tolling system use to identify vehicles without making them stop?
A Manual token checking at booths
B Paper permits issued at entry points
C Fuel-pump receipts linked to toll payment
D Automatic Number Plate Recognition through cameras Correct
Explanation
The system identifies vehicles by reading number plates through cameras using Automatic Number Plate Recognition. It is designed to eliminate conventional stopping at booths, so manual token checking, paper permits and fuel receipts are incorrect.
