  5. Do not increase your speed if you are going downhill.
  6. Pull over, ASAP, to a safe space and inspect your cargo to see if it shifted or needs to be moved around, so more weight is at the front of the trailer.
  7. Once you’re back on the road, maintain a slower speed while driving. Stay about 10 mph under the speed at which you noticed the trailer sway starting.
