Final answer:
When in a traffic lane, always keep clear of separation lines or zones, join or leave lanes at their termination, merge at a small angle to the flow of traffic, and never proceed against the direction of traffic.
Step-by-step explanation:
When proceeding in a traffic lane, you should adhere to certain safety guidelines and traffic laws to ensure safe travel for all road users. Firstly, you should keep clear of a traffic separation line or separation zone, as these are designed to direct the flow of traffic and keep vehicles apart to reduce the risk of accidents. Secondly, it is advisable to join or leave a traffic lane at the termination of the lane to avoid disrupting the flow of traffic. Additionally, when joining or leaving a lane, you should do so at as small an angle to the general direction of traffic flow as possible to merge smoothly and safely. Lastly, you must never proceed in the opposite direction of traffic flow, as this is illegal and extremely dangerous. By following these guidelines, you can contribute to making the roads safer for everyone.
