I hate to rain on everyone’s parade, but it is possible to not entirely close the hood on most cars without engaging the safety catch. However, since the danger of a hood opening on the road is so high and the risks so great, the hood latch operating mechanism and the safety catch system should be checked out thoroughly.
If it turns out that the young lady just didn’t close it, I strongly recommend that this be used as an educational opportunity. No opportunity to prevent this from happening again should be overlooked.
