You do not need to judge distance in metres while you drive. You just need a simple timing trick that works at any speed: the three-second rule. Here is how it works and when to give yourself even more room.<\/p>\n<h2>How the three-second rule works<\/h2>\n<p>Pick a fixed point ahead, like a sign, a pole, or a shadow across the road. When the back of the vehicle in front of you passes that point, start counting: one thousand one, one thousand two, one thousand three. If you reach the point before you finish counting, you are too close. Ease off and try again until a full three seconds pass before you get there.<\/p>\n<p>The beauty of counting time instead of measuring distance is that it scales automatically. At higher speed, three seconds covers more ground, which is exactly what you need. You get the right gap without doing any math.<\/p>\n<h2>Why three seconds<\/h2>\n<p>Three seconds is roughly the time it takes an average driver to notice a problem, decide to brake, and start actually slowing down. It is your reaction buffer. If the car ahead stops suddenly and you are only one second back, you are already too late. At three seconds, you have room to respond instead of react.<\/p>\n<h2>When to make it four, five, or six<\/h2>\n<p>Three seconds is the minimum for good conditions. Add more time whenever stopping gets harder or seeing gets worse:<\/p>\n<ul>\n<li><strong>Rain or wet roads:<\/strong> at least four seconds. Wet pavement is most slippery in the first few minutes of rain.<\/li>\n<li><strong>Snow or ice:<\/strong> six seconds or more. Braking distance on ice can be many times longer than on dry road.<\/li>\n<li><strong>Night or fog:<\/strong> extra time, because you see hazards later.<\/li>\n<li><strong>Behind a large truck or bus:<\/strong> more room, because you cannot see around it to what is coming.<\/li>\n<li><strong>Being tailgated yourself:<\/strong> increase your own gap so you can brake gently and give everyone more time.<\/li>\n<\/ul>\n<h2>Space is the only margin you control<\/h2>\n<p>You cannot control the driver ahead of you, the weather, or a deer stepping onto the road. The one thing you always control is how much room you leave. That space is what turns a sudden problem into a non-event. Build the three-second habit now and it protects you every single drive.<\/p>\n<p>Following distance is a favourite topic on the G1 rules section.
