Final answer:
Signaling for a turn or lane change should be done at least 100 meters in advance, with the distance increasing with higher speeds for safe driving.
Step-by-step explanation:
When considering traffic safety and the rules of the road, it is important to anticipate your actions to other drivers. Specifically, signalling your intention for a turn or lane change should be done well in advance. Although the exact distance can vary depending on the driving speed and road conditions, a general rule of thumb is to signal at least 100 meters (about 30 seconds) before making a turn or lane change, in urban areas. On highways or at higher speeds, the distance should be greater, allowing more time for other drivers to react to your signal. This not only is a legal requirement in many places, but also a good practice for safe driving. Failure to signal properly can lead to accidents and misunderstandings on the road. Always be aware of your environment and err on the side of caution when signalling to change lanes or turn.
When signaling a turn or lane change, it is important to indicate your intentions to other drivers in advance. The general rule is to signal at least 100 feet before you make the turn or change lanes. This gives other drivers enough time to react and adjust their own driving accordingly. However, in some states, the law may specify a different distance, so it's important to check your local regulations.
