We have a significant senior population in Florida and I know that seniors resent any implication that they are not as fast or as agile as someone who is younger. But the fact remains that it's probably true. And, it also remains that it is actually a factor in many accidents that occur involving pedestrians who are older.
We have a lot of roads here that are very wide and sometimes seniors if they don't start across the road promptly they may not have enough time to make it in time. We've actually handled fatalities in our office under exactly this same situation.
Sometimes the quickness of judgement, the ability to perceive the speed, distance and trajectory of an oncoming car can be difficult particularly as someone ages and when you add night time to that mix it becomes even more of deadly combination.
The reality is that seniors most often don't move as quickly, their vision isn't quite as sharp and their reaction and judgement of oncoming vehicles isn't what it used to be. And, these can combine to leave them vulnerable for being injured in a pedestrian crash.
