Final answer:
The handbook recommends signaling for at least 5 seconds before changing lanes on a freeway.
Step-by-step explanation:
The handbook recommends signaling for at least 5 seconds before changing lanes on a freeway.
Signaling for 5 seconds allows other drivers to be aware of your intention to change lanes and gives them enough time to adjust their speed and position accordingly. It is important to signal early, consistently, and clearly to ensure the safety of everyone on the road.
Additionally, signaling for a longer duration may not be necessary as it can confuse other drivers. The recommended 5-second duration balances the need for clear communication while minimizing the potential for confusion.
