What should you always do before accelerating after braking?

Before accelerating after braking, it's essential to check your mirrors for traffic to ensure a safe maneuver. This action helps you assess the surrounding environment and confirms whether it is safe to proceed. By looking in your mirrors, you can identify any vehicles or obstacles that may be coming up from behind or might be at your sides, which is crucial for maintaining safety on the road.

This practice is critical regardless of the circumstances shortly after braking, as it allows you to be fully aware of your surroundings and helps prevent accidents that might occur due to unforeseen traffic movements. It's part of the broader principle of always being vigilant while riding.

The other options emphasize different safety aspects while riding but do not specifically address the immediate requirement of ensuring safety after braking. Signaling your turn and checking tire pressure are vital for safe riding but aren’t directly related to the actions taken immediately before accelerating after a stop. Revving the engine does not contribute to safety and might distract you from proper observation before moving again.
