Final answer:
The bridge ahead allows room for only two lanes of traffic. Approach with caution.
Step-by-step explanation:
The statement 'The bridge ahead allows room for only two lanes of traffic. Approach with caution.'
The statement is true. The bridge ahead can accommodate only two lanes of traffic, meaning that there is not enough space for vehicles to travel side by side in additional lanes. Therefore, drivers should approach the bridge with caution to ensure the safety of the traffic flow.
