The mistakes that fail most people

Most failures come from the same handful of topics, not from obscure trivia. These are the rules students miss most often on the Illinois test: - Right of way at intersections and four-way stops - Illinois speed limits and school-zone rules - Winter and wet-weather driving - Alcohol and drug laws (zero tolerance under 21) - Road signs, signals, and pavement markings The fix is simple: practice realistic questions, read the explanation for every miss, and re-drill any topic you score below 80% on until it sticks.
