A cell phone violation is a 5 point violation.  It’s a big chunk of points, almost half of your allotted 11 total.  If this is the only violation on your record then a suspension is highly unlikely.  Of course like any violation, adding more points to an existing point on one’s record could be a problem.  Commercial drivers should be even more careful with these as an accumulation of multiple convictions can quickly lead to loss of commercial privileges.
