and this was from fhwa. >> i would say there is still much more we need to learn about this. the approach we are taking so far is that we try to promote good behavior from drivers comes a for instance if we implement a technology say for instance departure warning would promote you use your blinker and there are some studies looking at that and see that it actually helped drivers use their blander even more because they didn't get the warning every time they left their name. we are also addressing it if you take the brake technology has such we do not want to encourage behavior where you know the car will break so we don't have to pay attention to we have intentionally made the break intervention harsh and very late so we put it outside of your comfort zone so if you are an attentive driver you will think you are about to crash and we've studied that using driving salaries to understand that we promote that peter in the sense that yes, the driver will break if it knows it is about to impact something the driver will actually break the for the system does so we are approaching

go to the first table, fhwa. >> we have a couple questions here. the first one is for dr. sotestrom. do you see ways to foster older drivers in assessment and reporting? >> that's a great question. one of the recommendations that came out of the last 2003 effort was that part of the curriculum in medical schools should be that this subject be on the table. as far as i know, it still has not been accomplished. when i was at the trama center for many years, i know it was not part of my modum to send you home with casts on your body and tell you not to drive. probably didn't even think about it. in canada and in the state of maryland we're going out to the university hospitals and their major departments and all the community hospitals, and other facilities to try to get to the physician -- to get physicians and clinicians to put this on their radar. we need to educate them to think if someone in front of you is 16, 96, or 116 is they just said they have a new symptom, they're on a new medication, i just am going to do something to them, where does driving fit into that e equ

. >> we'll go to the first table and fhwa. >> until you don't drive. think about it. we are going to all the community hospitals and other facilities to put this on their radar. they just said, i'm going to do something to them it is far from complete. they have no idea whether it is one or whether they have any obligations or the driver has any obligations about reporting or talking to the nab or mba. >> you said we are pretty far along the pablg to some extent contradicts what i previously heard. we have a solid understanding that most significantly predict the risk of an at-fault crash. those are the actual tools. tools need to have certain properties where you cut and say who passes and who fails is a skien tiff yigs decision i don't think we are that far away, honestly. >> i think question need more science. what do we need to do to get to the point of who should be using that tool? when will we know that? >> rather than pick an age, our practice has been for years we use it when we have drafers referred to us in which there are indications of how old you are but
