With a sweeping stay-at-home order in effect across the Bay Area to try to slow the spread of coronavirus, businesses that stay open and people who are out and about during the next three weeks for anything other than an “essential” task or function are, technically, subject to a misdemeanor citation under the California Health and Safety Code.

In reality, that is far from how the order will be enforced, according to numerous local law-enforcement officials. For starters, there are an array of allowances and circumstances for who can be out and why— including walking the dog, or going on a hike or bike ride, as long as there is social distancing — it would be difficult to quickly discern a violation.
