Why: Marijuana acts similarly to alcohol by slowing down your reflexes and reaction time, rather than speeding them up. It impairs your ability to judge time, speed, and distance, making you a less safe driver.
Why: Marijuana is the second most common drug found in drivers involved in accidents, right after alcohol. It negatively impacts reaction time, coordination, and judgment.
Why: According to the official driving manual, you should return to your lane only after you can clearly see both headlights of the vehicle you just passed in your rearview mirror. This ensures you have left sufficient space and can merge safely.
Why: When driving behind someone who is distracted, you need more time to react to their unpredictable behavior. Maintaining a 3 to 4-second gap provides a necessary safety buffer.
Why: In Connecticut, traffic fines for speeding in work zones are doubled. This strict penalty is enforced to ensure the safety of road workers and other drivers in these vulnerable areas.
