Final answer:
In most situations, vehicles should be passed on the left side, with left-side passing being a common traffic rule. Safety and clear lanes are essential when passing, and local rules should always be observed.
Step-by-step explanation:
In most situations, you should pass another vehicle going in the same direction on the left side. This applies to bicycles, cars, and other types of vehicles. Passing on the left is a common rule of the road in many countries. However, it's important to note that some countries drive on the left side of the road, and in those locations, you would typically pass on the right.
It is also essential to consider the circumstances when you intend to pass. You must ensure that the lane you are moving into is clear and that it is safe to do so. Checking for any road signs or local laws is a crucial aspect of road safety. Sudden movements without proper signaling and observation can lead to dangerous situations. By following the rule of passing on the left, drivers can maintain a predictable flow of traffic and reduce the likelihood of accidents.
