This time of year, near the equinox's, the angle of the sun is almost directly aligned with east to west orientated roads after sunrise and before sunset. So, if heading east in the morning or west in the evening along east/west roads you can expect a significant glare. For the next week or so, you can expect on sunny days, glare and potential slowdowns from 730am-800am or so in the morning and from 700pm-740pm in the evening.
