Question:

Why dont semi truck trailers have anti-lock brakes?

They‘re always jackknifing and sheet. Whats up with that? My 1989 BMW motorcycle has anti-lock brakes, but brand new semis go around rolling on top of Miatas for no reason. So, wtf is going on, mang?

Answer:

lactose free milk means that the lactose (the part of cow milk that many people are allergic to) has been removed or neutralised. soy milk is made by processing soy beans, and adding artificial calcium etc,. My son reacted to cow's milk, and i didn't like the high sugar content in rice, oat and soy milk. He was on goat milk (not cheap, but an excellent alternative) until he was about 5 when he outgrew his milk problems. Try lactose free milk to see if she has a reaction. Speak to the doctor nutritionalist about your alternatives.
Many, if not most, DO have anti-lock brakes.
Anti-lock brakes are great but you simply cannot overcome the laws of physics. If you get a 70,000 lbs. object traveling down a road - particularly a wet or icy road - and then radically change the angle of the tractor and trailer, it can still jackknife whether or not a truck has ABS. Want to reduce jackknifing? One way may be to start prosecuting drivers who swerve in front of heavy trucks.
All new trucks are now required to have anti lock brake systems. Some manufacturers have been installing them for several years but the reason they're still jackknifing is that the law only went into effect one year ago so there are still a lot of trucks out there without ABS.
yep, lactose free milk is still cow's milk based, but has the lactose removed from it (lactose only means the sugar chain in milk). This will not be suitable if your child has a true milk allergy. Soy milk contains no cow's milk. You could ask to have your child retested to ensure it is a true milk allergy and not just a lactose allergy? Talk to your doc tho.
