What is necessary when you enter traffic from a stop (away from the curb)?

To enter traffic from a stop safely, it is essential to have a large enough gap to accelerate to the speed of the moving vehicles. This allows you to merge into traffic smoothly without causing disruptions or hazards for yourself or other drivers. If the gap is too small, it could result in a dangerous situation, as you may not have enough time to reach the required speed before being overtaken by other vehicles.

While signaling before entering traffic and observing traffic signals are also important elements of safe driving, having sufficient space to merge safely is the most critical consideration. As for only looking to the right, it is necessary to check for traffic in both directions to ensure a safe entry. Therefore, ensuring a large enough gap is the key factor in this scenario.
