Warped rotors
allignment
Tire out of balance or bent wheel.
Probably i would go for wheel balance and maybe check your wheel bearings rotors will not make it shake because of speed
bent drive axle or axles
usually steering shakes over 60 mph is due to front tires needing to be balanced unless you have something more serious going on.
My steering wheel shakes what could this mean? _____ try getting your car re-aligned.
Yes, you can still drive it. You may have a tire out of balance or a wheel bearing getting bad. However, have a mechanic check it out soon.
Tire out of balance, bent wheel, belt broken in tire, loose or worn steering components, loose wheel bearing, loose lug nuts, or suspension parts worn.
If it shakes just driving at around 50 mph then the tires need balancing. If it shakes when stopping you have a warped rotor. Edit: tire balance problems are most noticeable starting at around 35 mph. Balance problems can be undetectable by 50 mph. Can also be a bad tire which will be more noticeable usually at slower speeds. Steering wheel shake normally indicates a problem with the front end while a shake felt in your feet and/or the seat will be in the rear. Shake while braking will usually be a rotor problem, however can be a bent hub or spindle and even loose steering parts. Need to take to a qualified tech for further diagnosis.

Be sure to check suspension components. Namely the tie-rods...
