Final answer:
The most crucial step in changing lanes safely is ensuring that the destination lane is open, including checking all mirrors and blind spots, and signaling correctly. Vehicle speed does not always adhere to speed limits, and it's generally unsafe to cross a road with a car 28 meters away, as you may misjudge its speed.
Step-by-step explanation:
The most important step in safely changing lanes is ensuring that the lane to which you plan to move is open. This involves checking your mirrors, including the rearview and side mirrors, and performing a shoulder check to spot any vehicles in your blind spot. Additionally, signaling correctly is essential to inform other drivers of your intentions.
It is important not to decrease your speed abruptly, as this might cause the drivers behind you to react unexpectedly. When it comes to assessing road safety, such as when a rabbit might cross the road, considerations about traffic conditions and vehicle speeds are crucial. Vehicles do not always travel at the prescribed speed limit, and it is not always safe to cross a road, particularly outside of a pedestrian crossing.
The color of your car does not determine the speed at which you are traveling. Lastly, when a car is traveling towards you, and it is only 28 meters away, it is not generally safe to walk across the road, especially if you cannot accurately judge the car's speed and if there is no designated pedestrian crossing point.
