This study is from this year.

If the NHTSA is saying it's a non-issue then why don't we listen??? Their whole existence revolves around traffic safety.

Now, I understand why you would want to keep people who are stoned off the road regardless, but unless you're going to employ a zero tolerance policy accross the board, I don't think Marijuana users are who we should be investing any resources into keeping off the roads, especially when you consider the difficulty involved in measuring and testing intoxication.

Polak, in short they NHSTA says more study is needed.

But even as drinking and driving continues to fall, use of illegal drugs or medicines that can affect road safety is climbing. The number of weekend nighttime drivers with evidence of drugs in their system climbed from 16.3 percent in 2007 to 20 percent in 2014. The number of drivers with marijuana in their system grew by nearly 50 percent.

A second survey, the largest of its kind ever conducted, assessed whether marijuana use by drivers is associated with greater risk of crashes. The survey found that marijuana users are more likely to be involved in accidents, but that the increased risk may be due in part because marijuana users are more likely to be in groups at higher risk of crashes. In particular, marijuana users are more likely to be young men – a group already at high risk.

Other studies using driving simulators and test tracks have found that marijuana at sufficient dosage levels will affect driver risk.

In short the answer, at least from your source, isn't in yet.
