It's different from the House version, which has a no-tolerance policy on drugs in a person's system while driving.
State Sen. Dick Sears says his committee felt that was too extreme, since there is no current measurable standard for drug impairment (for example alcohol has a .08 limit for drinking and driving, but there is no standard for drugs).
The Senate version says the amount of drugs in your system has to actually impair your ability to drive.
"Trying to make sure that if somebody is taking a drug as prescribed, which might actually help them to drive more safely, that they wouldn't be in violation of the law because of the words 'affected to the slightest degree," said Sen. Sears.
While the distinction between the two bills seems small, it may be a tough fight to hammer out a compromise by next Friday, when the session adjourns.
