As we pointed out in our parent study, Fullerton had by far the greatest number of dangerous intersections, despite having only the third-highest number of accidents. In fact, Fullerton had more than 2,100 fewer collisions than Anaheim, yet Anaheim did not have a single intersection in the top 50.

The two most dangerous intersections in Fullerton?  Euclid and Orangethorpe and Chapman and Harbor had the highest number of collisions of any crossing in the county and ranked two and three respectively in the top 50.

The four streets represented in these crossings were particularly problematic, as 15 of the top 25 in Fullerton were on at least one of these streets.
